NTFS Recovery software is known as a very useful data recovery tool for Windows operation system which supports the NTFS file system. NTFS Recovery program can easily recover any data from different hard disks and types of storage media-all USB and flash drives, various PC cards and memory sticks, multimedia cards and secure digital cards and so on. NTFS Recovery program has a simple and very powerful algorithm, so with the utility it possible to restore any lost data just very quickly and most effectively. Let's notice which advantages from using of the program we can take. First of all, NTFS Recovery program can recover different deleted files, including such as MS Office files, mp3, photos and zip files. So, NTFS Recovery program is definitely able to restore various sorts of files including electronic documents, pictures and others. This hard drive recovery tool is able to recover files from NTFS hard drives and has effective and very simple interface. Also this hard drive recovery program is quite well compatible with Windows operation system. Do you want to prevent information loss and protect yourself from wasting time and money? Recognize all the advantages of NTFS recovery tools just now. All you need is to download the program and try to use it. It is not a surprise for anybody that for different reasons some important documents and data are sometimes lost just for some reasons. This can be a really huge problem if you don't have a proper recovery tool for different types of documents and files. In this case it can lead to considerable inconveniences, and moreover it requires expensive solutions. The software is not just an ordinary data recovery system. It has some out-of-order functions and features. One of the most considerable features is that the software enables to remove the data concerning deleted files. You can ask what is the reason of the function? The answer is that with the function nobody will be able to recover the data deleted by you and use it in his own interests. NTFS Recovery is an utility for recovering lost and by chance deleted information. An application works in Windows system and restores the lost information on disks with the file system of NTFS. The program restores information quite simple, which was initially on hard disks, informative storage devices of digital cameras, flesh-maps, usb-drives and diskettes. Taking advantage of the utility, a user is able to return, seemed, forever lost files, including documents of Microsoft Office, digital pictures, mp3 composition and zip-archives, even in case when the initial table of disk sections is changed. With the program it is easy to make a partition recovery if it is needed. One of the great number of advantages of the NTFS Recovery is that it is a fully automatic utility for recovering any information from the damaged or reformatted disks. The program scans the damaged disk, restoring the primary structure of files and folders. NTFS Recovery program works in all situations: • Formatted or inaccessible disk • At the damaged table of sections • If a computer does not find a load disk • At the damage of surface of disks • Deleted and also lost different files and directories • Et cetera So, the NTFS Recovery utility is very powerful program for renewal lost and by chance remote information. An application works in the environment of Windows and restores the lost information on disks with the file system of NTFS. The program restores information, initially

This paper addresses the major challenges that large organizations face in protecting their valuable data. Some of these challenges include recovery objectives, data explosion, cost and the nature of data. The paper explores multiple methods of data protection at different storage levels. RAID disk arrays, snapshot technology, storage mirroring, and backup and archive strategies all are methods used by many large organizations to protect their data. The paper surveys several different enterprise-level backup and archive solutions in the market today and evaluates each solution based on certain criteria. The evaluation criteria cover all business needs and help to tackle the key issues related to data protection. Finally, this paper provides insight on data protection mechanisms and proposes guidelines that help organizations to choose the best backup and archive solutions.

During forensic examination, analysis of unallocated space of seized storage media is essential to extract the previously deleted or overwritten files when the file system metadata is missing or corrupted. The process of recovering files from the unallocated space based on file type-specific information (header and footer) and/or file contents is known as Data Carving. The research in this domain has witnessed various
technological enhancements in terms of tools and techniques over the past years. This paper surveys various data carving techniques, in particular multimedia files and classifies the research in the domain into three categories: classical carving techniques, smart carving techniques and modern carving
techniques. Further, seven popular multimedia carving tools are empirically evaluated. We conclude with the need to develop the new techniques in the field for carving multimedia files due to the fact that the fragmentation and compression are very common issues for these files.

In recent years, flash memory has become more widely used due to its
advantages, such as fast data access, low power consumption, and high
mobility. However, flash memory also has drawbacks that need to be
overcome, such as erase-before-write, and the limitations of block deletion. In order to address this issue, the FTL (Flash Translation Layer) has been proposed with useful functionalities like address mapping, garbage collection, and wear-leveling. During the process of using, the data may be lost on power failure in the storage systems. In some systems, the data is very important. Thus recovery of data in the event of the system crash or a sudden power outage is of prime importance. This problem has attracted attention from researchers and many studies have been done. In this paper, we investigate previous studies on data recovery for flash memory from FTL processing solutions to PLR (Power Loss Recovery) solutions that have been proposed by authors in the conference proceeding, patents, or professional journals. This will provide a discussion of the proposed solutions to the data recovery in flash memory as well as an overview.

Technical and tactical aspects of law enforcement agencies’ searches for deleted digital evidence are described with the assumption that fundamental knowledge of digital data storage and deletion methods can support better fulfilment of purposes of criminal proceedings in cases involving digital evidence. Although “effective deletion” and “effective recovery” of digital data appear to be opposites, they both are necessary to ensure the broadly understood safety. Fundamentals of data writing on magnetic hard disks and SSDs are clarified, while options for deletion of sensitive data and recovery of digital evidence of crime are presented for both storage technologies.

This paper studies control format indicator (CFI) estimation methods in 4G-LTE communication systems. CFI is an essential control signal in LTE, and must be correctly detected at the receiver to avoid degraded system performance. The standard method of CFI detection involves the use of the Maximum Likelihood (ML) estimation criterion. Unfortunately, ML decoding performance relies on accurate channel estimation, and as a consequence may result in poor CFI decoding when channel estimates are poor. To improve CFI detection in severe fading channel conditions, a time-domain decision rule that requires no channel estimation, is proposed. Results show that when compared with the ML approach, the proposed method reduces the probability of CFI estimation error in the form of reduced block error rate.

Structural mapping in digital forensics helps the data recovery process by constructing potential layouts of files on disks where file-systems are lost or damaged, based on the layout of the file and on the particular features of each file format. The approach is particularly useful on fragmented file-systems, where data may be split over several areas. We are presenting a new and efficient approach for performing structural mapping of files in the data forensics process, by analyzing a database of file types used in the freeware software TrID and proposing an efficient model, based on regular expression matching, for achieving our goal. The proposed method is based on an extended model of the Aho-Corasick automaton that supports different types of constraints and also employs an XML-to-RegEx parsing engine that converts signatures from their native format in the TrID software to the regular-expression format used in our custom-built automaton. Experimental results performed in real-world scenarios with damaged filesystems have shown that our approach can significantly improve accuracy by building a potential map of fragments for the lost files, on top of which different heuristics may be employed for the final reconstruction of the documents, with very little impact on performance compared to the original automaton implementation, making this method a powerful and useful instrument for achieving better data recovery as part of forensic investigations.

Recently Edge Computing paradigm has gained significant popularity both in industry and academia. With its increased usage in real-life scenarios, security, privacy and integrity of data in such environments have become critical. Malicious deletion of mission-critical data due to ransomware, trojans and viruses has been a huge menace and recovering such lost data is an active field of research. As most of Edge computing devices have compute and storage limitations, difficult constraints arise in providing an optimal scheme for data protection. These devices mostly use Linux/Unix based operating systems. Hence, this work focuses on extending the Ext4 file system to APEX (Adaptive Ext4): a file system based on novel on-the-fly learning model that provides an Adaptive Recover-ability Aware file allocation platform for efficient post-deletion data recovery and therefore maintaining data integrity. Our recovery model and its lightweight implementation allow significant improvement in recover-ability of lost data with lower compute, space, time, and cost overheads compared to other methods. We demonstrate the effectiveness of APEX through a case study of overwriting surveillance videos by CryPy malware on Raspberry-Pi based Edge deployment and show 678% and 32% higher recovery than Ext4 and current state-of-the-art File Systems. We also evaluate the overhead characteristics and experimentally show that they are lower than other related works.

File-carving, as part of the data recovery process, is a topic of great interest due to its potential to minimize cost impact in business environments, where the losses are significant every year, according to public reports. Starting with a modified version of the signature database of TrID, a long-established file-identification utility, and implementing a multiple-pattern matching algorithm that extends the Aho-Corasick automaton, we propose an approach suitable for multi-core systems for performing carving using complex patterns, that describe filetypes more accurately, making it also suitable for digital forensics. The experimental results have shown that our approach performs better and identifies data with greater accuracy, with lower than 3% performance degradation in the processing bandwidth of the original approach.

Data can be lost from your computer hard drive due to various reasons and data recovery is the process of recovering lost data from the hard drives using fully automated recovery tools such as disk recovery software. This software can be used by anyone and does not need any professional experience. Disk recovery software scans the entire hard drive and get back deleted files. Vancouver, Canada, 07.07.2017-Data recovery is the process of getting data back from corrupted or inaccessible storage media when it cannot be accessed normally. Often the data is recovered from hard disk drives. Data recovery is needed when there is a physical damage to the storage device or when files system is not working with the operating system. Another case when recovery of data is needed is when the hard disk fails. In any of the situation data can be easily recovered. Data recovery is also needed when files are deleted from the storage media. Normally deleted files are not erased from the computer immediately and the files can be later restored. Data recovery software is the software that is used in the recovery of deleted files and data stored in the hard disk drive of any computer. The process of undelete is made possible and easy through this software. It provides a fully computerized method of recovering lost data and deleted files from corrupted disk. Recovering lost data and repairing inaccessible disks and partitions can be done by any person by themselves. Using the right disk recovery software, people can now do things which are done by data recovery professionals and that too at its best. Disk Recovery Wizard is quality software, which offers a complete set of recovery tools for successfully repairing partitions that are corrupted and bring back inaccessible drives back to use. Disk recovery makes it easy recovering lost data from corrupt hard drives and restoring disks. Disk recovery wizard make the tough task of data recovery look simple. Disk recovery software scans the hard drive very carefully and locates all partitions and recovers all files and data. Disk Recovery Wizard gets all files and data and also removes problem with partition tables and file system structures on just about any kind of storage device. Disk Recovery Wizard does not only search for deleted files that are to be recovered, instead it scans the entire hard drive or memory card to locate every file that may possibly be recovered.

In online or offline scenarios, from years on, a large number of text-data are generated from different web sources. Mainly incoherent and unstructured format is the huge amount of data, so hard to process via the available computer machines. A large number of unknown objects can be examined in an uncontrolled classification method. Text categorization involves learning methodology which is applied in areas such as linguistic identification, data recovery, opinion mining, spam filtering and e-mail routing, etc. The categorisation of text can also be considered as a mechanism for the labeling of different documents from natural corpus. The text classification by various Mechanisms of Machine Learning meets the challenge of the vector's high dimensionality. The latent semant indexing method can solve this problem by replacing the individual words with statistically derived conceptual indices. We propose a twostage feature selection method with the aim of improving the accuracy and efficiency of categorizing. Firstly, to reduce the dimension of the terms, we apply a new method of selection and then build a new semantinal space, between terms, which is based on the latent semant indexation method. We can find that our two-stage feature selection method works better with certain applications involving the categorisation of the spam database.

In this new era of information and technology computers play an essential role in our life. Most critical data are being stored on the computer’s hard disk. It can give you nightmares if your hard drive fails to work or has crashed and you cannot do the disk recovery. You can follow certain tips that will help you to avoid future hard drive crashes and data loss.
If you ever found an error message on your computer screen that flashes “missing system file” with a black screen and your computer doesn’t boot at all, don’t panic your data is still there. You just need to repair your corrupted Windows with the help of a Windows CD. In this case don’t go for a system recovery, it may format the complete hard disk and reinstall Windows.
Always try to use USB caddies to pull out the data from your computer and store a back up copy. These USB caddies are very helpful and should be used if you want to make some changes in your computer hardware.
If you start you computer and it says “chkdsk”, it might be some problem with your hard disk. Turn off your computer, remove the hard disk and create a back up copy using a USB caddie, after that switched on your computer. If the same message is displayed in your computer frequently you should consider your hard drive to be checked or replaced.
If you have accidentally deleted any data from your computer and you have also emptied your recycle bin, then don’t go directly to internet to download any software to recover your lost data. Always turn off your computer, connect your hard disk to a separate system using a USB caddie, install data recovery software into that separate system and scan for the lost data from that system. After finding the data save it in the system through which you were searching for the lost data.
If you hear clicking noise from your hard disk, immediately shut down your computer. If your computer is not responding do a hard shutdown. Never try to restart the computer immediately; it may cause data loss. Take time to let the hard drive cool, then connect it to a caddie and extract the data and store them on different hard drive and try to recover data.

Recent advances in the massively parallel computational abilities of graphical processing units (GPUs) have increased their use for general purpose computation, as companies look to take advantage of big data processing techniques. This has given rise to the potential for malicious software targeting GPUs, which is of interest to forensic investigators examining the operation of software. The ability to carry out reverse-engineering of software is of great importance within the security and forensics fields, particularly when investigating malicious software or carrying out forensic analysis following a successful security breach. Due to the complexity of the Nvidia CUDA (Compute Unified Device Architecture) framework, it is not clear how best to approach the reverse engineering of a piece of CUDA software. We carry out a review of the different binary output formats which may be encountered from the CUDA compiler, and their implications on reverse engineering. We then demonstrate the process of carrying out disassembly of an example CUDA application, to establish the various techniques available to forensic investigators carrying out black-box disas-sembly and reverse engineering of CUDA binaries. We show that the Nvidia compiler, using default settings, leaks useful information. Finally, we demonstrate techniques to better protect intellectual property in CUDA algorithm implementations from reverse engineering.

No one can predict or control when a force of nature will occur. To illustrate the prevalence of manmade attacks (e.g. hackers) and their financial motivations, Morgan (2018) calculated that by next year, a business will become victimized by a ransomware attack every 14 seconds and if your math is only minimal you will calculate that to be at least 4 times per minute! The message is that we are not immune and please don’t take that calculation to mean that hackers are waiting idly by for 2019-they are on their game now and they are good at it.

There are plenty of software tools that claim to recover data from damaged and corrupted disks, after accidental format, deletion, repartitioning or crash. Some of them are free, and some cost well over a thousand dollars. But are these tools worth it? Read my story of trying different data recovery software to save data from a constantly degrading hard disk. It all started with a Windows crash. The blue-screen occurred literally from the blue sky. After rebooting and trying to open a Word document I was working on, I've got a corrupted file. There wasn't much text typed, so I simply created a new one and went on. However, the problem persisted. I started getting intermittent crashes every once in a while, every time with more and more corruption. Running scandisk found and recovered multiple 'lost' chunks that were essentially useless. What's worse, I started seeing 'bad' sectors in the scandisk reports. Slowly, I began realizing that there might be something wrong with the hard disk. I would probably be realizing the problem for some more time, but one day the system simply didn't boot after a crash. Booting from the Windows installation DVD, I was able to do some repairs to the disk that didn't make it boot anyways. So I went ahead and bought another disk to replace the failed one. Years of perfection ensured that the highest technologies made their way to Disk Recovery Wizard. Thanks to the proprietary low-level disk recovery engine, Disk Recovery Wizard will help you get your data back in the safest and most reliable manner possible. And then I realized a small problem. You see, I am writing a lot of texts in Microsoft Word, having over a thousand documents sitting on the hard drive, and that's not accounting for family photo archives and occasional Excel spreadsheets. I thought it would be a pity to lose all of this data, and started exploring my options. Did you ever try firing the " data recovery " queue in Google? You get a whole bunch of ads and SEO-optimized sites offering all sorts of stuff. Obviously, the first results lead to data recovery services. Ouch: expensive! Maybe I could try it myself, I thought, with something like data recovery software. The " data recovery software " search returned more of what I considered appropriate. Let's try the free stuff, I thought, and downloaded a free undelete tool. Nah; didn't even find any of my files. Obviously, there's something wrong with the file system. So I tried another data recovery software, and another one, and yet another one, with similar results. Suddenly, one of the tools could actually see my files! I clicked on one of the files, and immediately saw a preview of one of my Word documents. I went online and paid for that data recovery software. Needless to say I had all of my documents saved to the new disk in less than an hour! The data recovery software I successfully used to recover my documents and digital pictures is called Disk Recovery Wizard. You can get a copy of Disk Recovery now. It could successfully locate my Office documents and digital pictures on a hard disk with a corrupted and then 'repaired' file system by scanning the surface of the disk and looking for byte signatures typical for documents and digital pictures. This turned to be an effective process that saved me hour of work and years of memories. Warmly regarded and highly recommended! www.wizardrecovery.com

Raid data recovery is definitely one of the complex procedures that any company for data recovery could perform. Frequently, the problems are somewhat compounded by the actions of the client right before sending the drives in for the recovery. Most of the users actually feel that it is somewhat essential to try and then recover the data alone or simply repair the array through different utility of the system and it could be find once the data is not critical. Actually, the IT professionals totally have lots of pressure being placed upon it when a catastrophic system failure takes place. It is actually their job to ensure that the entire systems are up and running. Mostly, out of panic, the process of troubleshooting are then initiated just to correct the problem itself. Most of the time, such processes could only make up a bad situation worse. At some instances, they could render the data unrecoverable. So, it would be best to keep in mind what this data may consist of in the average corporate milieu. You might be dealing with information costing hundreds or thousands of dollars for the resources and labor. Most of the data included in it could not be duplicated. Its intellectual value could be in million dollars. The corporate executives do not really care to hear about how such failure occurred or what string of events happened that led up to the crash of the server. They do not actually care for hearing the technical jargon, as you could try explaining what had happened, and hope they may understand that it really wasn't your fault at all. On the other hand, instead of taking up the chances alone, simply call a professional who could do data recovery. RAID data recovery could be somewhat expensive. The only thing is that, in most cases, it is less costly rather than trying to remake the data, which has been lost. There is somewhat a good set of procedure that most of the professionals for data recovery follows, most especially when performing recovery works. Such procedures are then expanded and followed when dealing with the Raid recovery. Actually, the first step of RAID data recovery is by ensuring that the entire drives are functional. It is important that the drives are fully functional with regards to completing the recovery in a proper way. Therefore, before you start with the process, considering things like such is essential.

This paper presents a 20 Gb/s injection-locked clock and data recovery (CDR) circuit for burst mode applications. Utilizing a half rate injection-locked oscillator (ILO) in the proposed CDR circuit leads to higher speed operation and lower power consumption. In addition, to accommodate process, voltage, and temperature (PVT) variations and to increase the lock range, a frequency locked loop is proposed to use in this circuit. The circuit is designed in 0.18 µm CMOS and the simulations for 2 7-1 pseudo random bit sequence (PRBS) show that the circuit consumes 55.3 mW at 20 Gb/s, while the recovered clock rms jitter is 1.1 ps.

Each year, the President of the University of New Haven selects a professor to give a "Last Lecture." The challenge is to offer a talk that would, in the speaker's view, be appropriate if it were the last lecture they could ever give. Glenn McGee was selected to give the lecture for 2016. The title of his lecture is "Lost"; its premise is that our digital identities are far more easily lost than we realize.
