The md5 algorithm is an algorithm that is able to turn arbitrarily different lengths of messages into a 128-bit digest. Each digest of corresponding to the message is unique, and it is difficult to calculate the message itself by digest. It specifically elaborates the realization of the principle and the security of the md5 algorithm. For the brute-force method and collision attack mean, improvement and implementation of the md5 algorithm in user security application is proposed. Changing the structure of the plaintext and ciphertext can ensure the security of the user security.

Over the past two decades, significant researches have been done in analyzing the md5 algorithm to address its collision problem. This paper enhanced the original md5 by adding four logical operations to increase the security of the message to become free from collision attack. To test the enhanced algorithm, different data with collision problems using the md5 Collision generator were used. The avalanche effect was measured, and the result provided more than 50%-bit change. The enhanced md5 was also tested against dictionary attack using online cracking tools and these tools failed to crack and revert the message digest into plain text. Overall, the enhanced algorithm mitigated the collision problem of md5.

Aiming at reducing the risk of data being intercepted and preventing deceptions in the electronic commerce, this paper proposes a method based on md5 and time which can effectively prevent the deception in data transmission. The method uses the traditional md5 algorithm to encrypt and validate important data, then verifying the validity and legitimacy of the data by using time.

md5 is a cryptographic algorithm used for authentication. when implemented in hardware, the performance is affected by the data dependency of the iterative compression function. In this paper, a new functional description is proposed with the aim of achieving higher throughput by mean of reducing the critical path and latency. This description can be used in similar structures of other hash algorithms, such as SHA-1, SHA-2 and RIPEmd-160. which have comparable data dependence. The proposed md5 hardware architecture achieves a high throughput/area ratio, results of implementation in an FPGA are presented and discussed, as well as comparisons against related works.

Duplicate detection, which is an important subtask of data cleaning, is the task of identifying multiple representations of a same real-world object and necessary to improve data quality. Numerous approaches both for relational and XML data exist. As XML becomes increasingly popular for data exchange and data publishing on the Web, algorithms to detect duplicates in XML documents are required. Previous domain independent solutions to this problem relied on standard textual similarity functions (e. g., edit distance, cosine metric) between objects. However, such approaches result in large numbers of false positives if we want to identify domain-specific abbreviations and conventions. In this paper, we present the process of detecting duplicate includes three modules, such as selector, preprocessor and duplicate identifier which uses XML documents and candidate definition as input and produces duplicate objects as output. The aim of this research is to develop an efficient algorithm for detecting duplicate in complex XML documents and to reduce number of false positive by using md5 algorithm. We illustrate the efficiency of this approach on several real-world datasets.

Cryptography is the concept used to enhance secure communication between two parties;these parties can be two persons in same building or two persons in different organizations of the world. Cryptography is said to be 100 % secure but every time attacker try to break the magic of cryptography. One loose point in cryptography is key transmission. It is most sensitive transmission in the field of cryptography. Many Techniques are proposed time to time to secure key transmission. Some techniques have shown good result up to some extent but not at all fully secured. In this paper we have proposed a key transmission technique to enhance security, Confidentiality and Integrity. We have described detailed algorithm to perform key transmission. Also we have compared the proposed algorithm with existing algorithms.

Video counterfeiting has become a major threat in today's digital environment, made worse by the widespread use of social media and sophisticated editing tools. There are dangers to one's mental health and wellbeing from this video modification. Advancements in technology, especially in artificial intelligence (AI), pose challenges to traditional techniques of video authenticity verification such digital signatures. The proposed objectives are to investigate the efficacy of cryptographic hash techniques like md5 for validation and to identify altered videos using machine learning algorithms. The work aims to determine the best method for verifying the authenticity of digital videos through extensive experimentation and analysis.

Change Data Capture from source system is the first step in the incremental maintenance of data warehouses and business intelligence and is a key component of ETL (Extract, Transform and Load) technique. Methods of CDC are currently available, namely, time stamps, differential snapshots, triggers, and archive log. Differential snapshots do not rely on the implementation mechanism of the information sources, and therefore demonstrates better universality and adaptability. Due to the lack of computing resources, the differential snapshots based on sort merge and hash partition are sometimes error and not effective. This paper proposes the differential snapshot of low cost and high efficiency which combines open source database and Hadoop MapReduce. The differential snapshot based data summary which is generated by the md5 algorithm is very effective but I/O cost is very heavy. So the paper proposes the SQL statement which queries the database while generating the tuples summary only once I/O. We implement the SQL statement on the open source database MySQL. In addition the parallel programming of MapReduce is used to find difference of database files which improves the efficiency and avoids the error. Experiment verifies the different performances among differential snapshot algorithms difference algorithm.

Due to their many applications, optical character recognition (OCR) systems have been developed even for scripts like Telugu. Due to the huge number of symbols utilized, identifying the Telugu words is a very complicated task. Pre-computed symbol features are stored by these types of systems to be recognized or retrieved from a database. Hence, searching of Telugu script from the database is a challenging task due to the complication involved in finding the features of the Telugu word images or scripts. Here, we implement a novel Telugu script recognition and retrieval approach based on a method called hash coded hamming (HCH). Hash coding will be used as a feature extractor and the hamming distance will be utilized as a replacement for conventional Euclidean distance in order to measure the similarity between query and database images. Simulation analysis shows that the proposed scheme has a superior performance to the conventional approaches presented in the literature.
