    A Survey of Hashing Techniques and its Applicability for Efficient Buffer Cache Management Abstract: Hashing is the convenient way to get access to an item based on the given key which is the requirement for efficient buffer cache management. Static hashing provides fastest access to an object at the cost of memory utilization, whereas sequential storage provides most efficient memory utilization at the cost of access time. To provide balance between two extremes dynamic hashing schemes are produced

  • Privacy Protecting Trademark Identification System Using Cloud

    Privacy Preserving Trademark Identification System using Cloud 1. Introduction Content-Based Information Retrieval (CBIR) is the field that constitutes representation of images, organizing and searching of images based on their content rather than annotations of image. CBIR, also known as query by image content and content-based visual information retrieval (CBVIR) is the application of computer vision techniques to the image retrieval problem, that is, the matter of checking out digital pictures

  • Message Digest 6 : Md6 Algorithm, How It Functions, And The Essentialness Of A Hashing Function

    1517 Words  | 7 Pages

    Abstract This report illustrates the Message Digest 6 (MD6) hashing algorithm, how it functions, and the essentialness of a hashing function. Besides, it depicts the qualities of this hashing capacity over its predecessor, and its present shortcomings. This paper will take an in-depth look at the specifications of MD6 hashing algorithm by introducing the readers to the design, efficiency, security, compatibility of MD6. Keywords – MD6; Message Digest 6; Hash Function; Cryptographic Hash.

  • The Use Of Recent And Modern Multimedia Devices

    Image perceptual hashing has been proposed to identify or authenticate image contents in a robust way against distortions caused by compression, noise, common signal processing and geometrical modifications, while still holding a good discriminability for different ones in sense of human perception Alongside watermarking, perceptual image hashing has emerged as an attractive way to verify the authenticity of digital images [1], [5], [6]. Also, image hashing and watermarking could be complementary

  • Using Encryption Algorithms That Can Be Used For Protecting Data

    1403 Words  | 6 Pages

    folders, storage devices, or entire volumes. Although encryption can be used to protect a variety of data types, there are many different encryption algorithms that can be used. The most common and popular encryption algorithms that are used include hashing, symmetric methods, and asymmetric methods. It is important to comprehend the underlying terminology, in order to gain a deeper understanding of the different types of encryption algorithms that is a “component for electronic data security.” 5

  • Encryption Is The Process Of Encoding Information

    alphabet. So if your original message read “Meet you at the cafe tonight” the encrypted message reads as follows: “Nffu zpv bu uif dbgf upojhiu”. Types of Encryption In encryption we have 3 different types ⦁ Hashing ⦁ Symmetric ⦁ Asymmetric Hashing: The first encryption method, called hashing, creates a unique, fixed-length signature for a message or data set. Hashes are created with an algorithm, or hash function, and people commonly use them to compare sets of data. Since a hash is unique to a

  • Authentication Of Critical Data Using Image Processing

    1683 Words  | 7 Pages

    encryption is to avoid drawing attention to the transmission of hidden information. Storing the critical data in its original format is subjective to many risks. The embedding algorithm is used to embed the secret information in the image selected. Hashing is used to secure the sensitive information. The project is about how to save the critical image and password using image encryption and steganography. Initially the user selects an image and enters the password. The image is now converted into binary

  • A Research Study On Global Variables

    Above you see an extract from the log in page, showing the heavy dependence on $_SESSION variables. These are required so much because they allow other pages to access the data. If I just used local variables I’d have no ability to transfer data between pages, and this is necessary to keep track of things like who is logged in or if even anyone is logged in. All SQL queries come back as associative arrays too, with each column entry being an element in the array, so they are very prominent. There

  • A Survey Paper On Exact And Hybrid String Matching Algorithms

    1689 Words  | 7 Pages

    A Survey Paper on Exact and Hybrid String Matching Algorithms Mohit Gupta UFID 90991438 Abstract and Introduction A string matching algorithm takes an input pattern and matches it against a given text. The algorithm aligns the pattern with the beginning of the text and keeps shifting the pattern forward until a match is found or end of the text is reached. String matching has a variety of applications like intrusion detection systems, information security, detecting plagiarism, bioinformatics
