In this paper, we propose a novel Deep Semantic-Asymmetric Hashing (DSAH) approach, which exploits semantic correlation between query points and their labels in a common semantic space to form more discriminative and similarity-preserving binary codes. Experiments show that DSAH outperforms current ...

Explore the key differences between hashing and encryption, understanding their purposes, methods, and applications in data security.
MD5 − MD5 is a 128-bit hash function that is widely used in software to verify the integrity of transferred files. The 128-bit hash value is typically represented as a 32-digit hexadecimal number. For example, the word "frog" always generates the hash "8b1a9953c4611296a827abf8c4780...

This is shown in the code given below −if (Hash::check('plain-text', $hashedPassword)) { // The passwords match... } Note that the check method compares the plain-text with the hashedPassword variable and if the result is true, it returns a true value....
In addition, a discrete optimization algorithm is proposed to solve the discrete problems. Our major contributions can be summarized as follows: 1. A novel supervised cross-modal hashing method, i.e., DSAH, is proposed to learn the discriminative compact hash codes for large-scale retrieval ...
