Mobile: (0) 9952649690 , Email: [email protected], web: www.jpinfotech.org Blog: www.jpinfotech.blogspot.com Our Branches in: Coimbatore | Salem | Bangalore | Mysore | Tanjore | Cuddalore | Villupuram | Chennai Identity-Based Secure Distributed Data Storage Schemes Secure distributed data storage can shift the burden of maintaining a large number of files from the owner to proxy servers. Proxy servers can convert encrypted files for the owner to encrypted files for the receiver without the necessity of knowing the content of the original files. In practice, the original files will be removed by the owner for the sake of space efficiency. Hence, the issues on confidentiality and integrity of the outsourced data must be addressed carefully. In this paper, we propose two identity-based secure distributed data storage (IBSDDS) schemes. Our schemes can capture the following properties: (1) The file owner can decide the access permission independently without the help of the private key generator (PKG); (2) For one query, a receiver can only access one file, instead of all files of the owner; (3) Our schemes are secure against the collusion attacks, namely even if the receiver can compromise the proxy servers, he cannot obtain the owner's secret key. Although the first scheme is only secure against the chosen plaintext attacks (CPA), the second scheme is secure against the chosen cipher text attacks (CCA). To the best of our knowledge, it is the first IBSDDS schemes where an access permissions is made by the owner for an exact file and collusion attacks can be protected in the standard model.

Generating Searchable Public Key Ciphertexts With Hidden Structures for Fast Keyword Search
 
03:11
Title: Generating Searchable Public-Key Ciphertexts with Hidden Structures for Fast Keyword Search Domain: Data Mining Key Features: 1. Searchable Public-Key Ciphertexts with Hidden Structures (SPCHS) for keyword search as fast as possible without sacrificing semantic security of the encrypted keywords. 2. In SPCHS, all keyword-searchable ciphertexts are structured by hidden relations, and with the search trapdoor corresponding to a keyword, the minimum information of the relations is disclosed to a search algorithm as the guidance to find all matching ciphertexts efficiently. 3. We construct a SPCHS scheme from scratch in which the ciphertexts have a hidden star-like structure. We prove our scheme to be semantically secure in the Random Oracle (RO) model. 4. The search complexity of our scheme is dependent on the actual number of the ciphertexts containing the queried keyword, rather than the number of all ciphertexts. 5. Finally, we present a generic SPCHS construction from anonymous identity-based encryption and collision-free full-identity malleable Identity-Based Key Encapsulation Mechanism (IBKEM) with anonymity.

Mystery of the Widow's Son - The Legend of the Craft
 
54:21
Hiram Abiff was busy working his Craft, when he suddenly found himself transported into the center of the Earth by Tubal-Cain, there to taste of the Tree of Knowledge. . . Who was the original 'Widow's Son'? That all depends on who you ask. This documentary explores a particular thread of Masonic history, namely the origin of the third degree, and the 'lineage' of the Craft. Sourced from some of the earliest manuscripts, and exploring certain facts not often brought to light, we shall see why the Mark of Tubal-Cain is an indelible stamp of heritage to the thoughtful Mason.

What Is A Bitcoin Wallet? - The Best Explanation EVER
 
04:06
This is a free sample lesson from 'The Secrets Of The Bitcoin Triangle' course, where you will 'Discover The 21 Fast Track Ways To Make And Save With Bitcoin (Starting From Scratch)'. You can sign up for the full course at: https://cryptoversity.krtra.com/t/r54RTiOWLIZa A Bitcoin wallet is a piece of software you use to communicate with the Bitcoin network and tell it when you want to send and receive transactions. The best way to understand a Bitcoin wallet is by comparing it to email. Once you have setup an email address you need some kind of software to allow you to send and receive emails to that address. Now this software may be an app on your phone, it may be an app on your laptop or it could even be an app you log into online. With email, you enter the username and password for your email address into the app and that’s how the Internet knows it’s really you that is sending and receive emails to that address. Now of course you tell everyone your email address and you have to do that in order for anyone to send you a message. But just because someone knows your email address, that doesn’t allow them to send email from that address. If they could that would be bad because then they could send emails pretending to be you and cause all kinds of problems. In order to be allowed to send email from a particular email address, you have to know the password. If someone finds out your email password then there’s nothing stopping them from logging in to your email app and sending messages. This is very similar to how a Bitcoin wallet works. Every Bitcoin account has two elements to it. One is called your public address, which is like your email address, and one is called your private key, which is like your password. So just like email, you can give anyone your Bitcoin public address and then anyone, anywhere in the world can send you some Bitcoin. They don’t need to know anything about you. All they need is that public address and they can send money to you. Your Bitcoin private key on the other hand is the one thing you must protect. It’s called your private key for a reason because you should never reveal this to anyone. If someone gets your email password, that’s bad because they can start sending emails from your address, but that’s not quite as bad as someone getting your Bitcoin private key because then they can steal all of your Bitcoins by sending them somewhere else. And just like email, once a Bitcoin transaction has been sent, it’s a one way trip. The only way to get it back would be for the person you sent it to to voluntarily send it back. Bitcoin literally works like digital cash. Once you’ve handed it over, the Bitcoin belongs to that other person. And the same goes for when you receive Bitcoin. Once someone sends it to you, it’s yours and no one can take it from you. The only way they could do that is if they knew your private key. And of course now you know never to give this to anyone.

Mobile: (0) 9952649690 , Email: [email protected], web: www.jpinfotech.org Blog: www.jpinfotech.blogspot.com Using cloud computing, individuals can store their data on remote servers and allow data access to public users through the cloud servers. As the outsourced data are likely to contain sensitive privacy information, they are typically encrypted before uploaded to the cloud. This, however, significantly limits the usability of outsourced data due to the difficulty of searching over the encrypted data. In this paper, we address this issue by developing the fine-grained multi-keyword search schemes over encrypted cloud data. Our original contributions are three-fold. First, we introduce the relevance scores and preference factors upon keywords which enable the precise keyword search and personalized user experience. Second, we develop a practical and very efficient multi-keyword search scheme. The proposed scheme can support complicated logic search the mixed “AND”, “OR” and “NO” operations of keywords. Third, we further employ the classified sub-dictionaries technique to achieve better efficiency on index building, trapdoor generating and query. Lastly, we analyze the security of the proposed schemes in terms of confidentiality of documents, privacy protection of index and trapdoor, and unlinkability of trapdoor. Through extensive experiments using the real-world dataset, we validate the performance of the proposed schemes. Both the security analysis and experimental results demonstrate that the proposed schemes can achieve the same security level comparing to the existing ones and better performance in terms of functionality, query complexity and efficiency.

Assassin's Creed: Brotherhood (The Movie)
 
02:47:09
Here's my newest movie, Assassin's Creed Brotherhood. Please note that this is not a spin-off. It's an important part of the AC story and should not be skipped. As before, the goal of these projects is to present the story in a way that non gamers can understand. This is done by including any cutscenes and minimal gameplay necessary to understanding what's going on. I will not cut anything that would lead to plot holes or confusion. I try to remove as many game indicators as possible, such as the HUD, and thankfully the AC series allows you to disable the HUD, but unfortunately that doesn't quite remove everything. There are still text prompts, sync notices, occasional button prompts, and sometimes the game itself bugs out and displays the HUD anyway. Thankfully, the story explains these things as being part of the Animus. My PC Specs and settings are: AMD Phenom II X4 965 Black Edition 3.4 GHz NVIDIA GeForce GTX 480 8 GB RAM 1280x720 @ 72Hz Max Settings 50 fps average frame rate 23.976 fps capture I tried running at 1080p, but I believe the HDD access for capturing 1080p in real time caused far too much lag.

Ethical Hacking Terminologies Following is A list of important terms used in the field of hacking. Adware Adware is the name given to programs that are designed to display advertisements on your computer. Adware displays or downloads advertising material such as banners or pop-ups when a user is online. Attack An attack is an action that is done on a system to get its access and extract sensitive data. Back door A back door, or trap door, is a hidden entry to a computing device or software that bypasses security measures, such as logins and password protections. Bot A bot is a program that automates an action so that it can be done repeatedly at a much higher rate for a more sustained period than a human operator could do it. For example, sending HTTP, FTP or Telnet at a higher rate or calling script to create objects at a higher rate. Botnet A botnet, also known as zombie army, is a group of computers controlled without their owners’ knowledge. Botnets are used to send spam or make denial of service attacks. Brute force attack A brute force attack is an automated and the simplest kind of method to gain access to a system or website. It tries different combination of usernames and passwords, over and over again, until it gets in. Buffer Overflow Buffer Overflow is a flaw that occurs when more data is written to a block of memory, or buffer, than the buffer is allocated to hold. Clone phishing Clone phishing is the modification of an existing, legitimate email with a false link to trick the recipient into providing personal information. Cracker A cracker is one who modifies the software to access the features which are considered undesirable by the person cracking the software, especially copy protection features. Denial of service attack (DoS) A denial of service (DoS) attack is a malicious attempt to make a server or a network resource unavailable to users, usually by temporarily interrupting or suspending the services of a host connected to the Internet. DDoS DDoS is a type of DOS attack where multiple compromised systems, which are often infected with a Trojan, are used to target a single system causing a Denial of Service (DoS) attack. Exploit Kit An exploit kit is software system designed to run on web servers, with the purpose of identifying software vulnerabilities in client machines communicating with it and exploiting discovered vulnerabilities to upload and execute malicious code on the client. Exploit Exploit is a piece of software, a chunk of data, or a sequence of commands that takes advantage of a bug or vulnerability to compromise the security of a computer or network system. Firewall A firewall is a filter designed to keep unwanted intruders outside a computer system or network while allowing safe communication between systems and users on the inside of the firewall. Keystroke logging Keystroke logging is the process of tracking the keys which are pressed on a computer (and which touchscreen points are used). It is simply the map of a computer/human interface. It is used by gray and black hat hackers to record login IDs and passwords. Keyloggers are usually secreted onto a device using a Trojan delivered by a phishing email. Logic bomb A virus secreted into a system that triggers a malicious action when certain conditions are met. The most common version is the time bomb. Malware Malware is an umbrella term used to refer to a variety of forms of hostile or intrusive software, including computer viruses, worms, Trojan horses, ransomware, spyware, adware, scareware, and other malicious programs. Phishing Phishing is an e-mail fraud method in which the perpetrator sends out legitimate-looking emails, in an attempt to gather personal and financial information from recipients. Phreaker Phreakers are considered the original computer hackers and they are those who break into the telephone network illegally, typically to make free long distance phone calls or to tap phone lines. Rootkit Rootkit is a stealthy type of software, typically malicious, designed to hide the existence of certain processes or programs from normal methods of detection and enable continued privileged access to a computer. Social engineering Social engineering implies deceiving someone with the purpose of acquiring sensitive and personal information, like credit card details or user names and passwords. ************************ All these videos Tutorials for educational purpose only, Don't misuse it.
