In his case study, Martin provides a detailed account of the events leading up to the explosion, emphasizing the unnecessary loss of one hundred and eleven lives. The community’s failure to take effective action despite prior knowledge of the mine’s dangerous conditions is both terrifying and shocking (Stimulant 31). The purpose of this case study, […]

An evacuation center Is a place designed and constructed to protect people living In vicinity during an emergency, especially during natural disasters such as typhoons, flooding, and earthquake. The level of occupant protection provided by a space specifically designed as a shelter Is Intended to be much greater than the protection provided by buildings that […]

Data Mining Project Introduction This report discusses the challenges faced by banks in managing debt and repaying loans. The banks are currently struggling with borrowers who fail to fulfill their loan repayment commitments despite making promises. The banks are determined to prevent this issue from recurring and have shared a dataset of 2000 customers who […]

This includes collective plans and blueprints right from the conceptualization of the research project, data gathering on the existing system, knowledge requirements on different technologies included in the system, design and development of the system, up to the software evaluation. The researcher used Prototyping as the method for development. This type of approach of evildoing […]

Doing some research about the “Zimmermann Telegram” (image shown below) and then answer the following questions: Which technique was used in encrypting this telegram: substitution, transposition/permutation or stenography? If you were an intelligence officer, what lessons you could learn from this “weak” encryption? (There is no need to decrypt the telegram yourself. It requires lots […]

It is our understanding that your organization has formed a partnership with another entity handling sensitive information. To ensure maximum security, we suggest using the latest cryptographic technology, specifically Symmetric Encryption. We strongly advise your Chief Information Officer to consider implementing this precautionary measure, considering the sensitivity of both establishments’ materials. Symmetric Encryption is an […]

Despite the constant advice to update passwords for better personal security, individuals tend to prioritize memorizing numerous account passwords over safeguarding their accounts from possible hacking attempts. Recent reports emphasize the significance of password management and the need to be vigilant in safeguarding your online presence, as mishandling or neglecting passwords can prove to be […]

Wired Equivalent Privacy (WEP) is a security protocol utilized in wireless networks to encrypt data during transmission. It is a component of the IEEE 802.11 wireless networking standard. Although WEP was an initial effort to secure wireless networks, there are now more effective alternatives available. WEP provides three choices: off (no security), 64-bit (weak), and […]

Abstract The ever-increasing demand of users for various wireless communication services has lead to the development and to the coexistence of different, and often incompatible, wireless networks. Each one of these wireless networks has its own unique application and characteristics, as compared to other networks. Moreover, each network continues to evolve individually, most frequently not […]

This is an area of substantial interest In database because we know that, the use of database Is coming very important In today’s enterprise and databases contains Information that is major enterprise asset. This survey was conducted to identify the issues and threats in database security, requirements of database security, and how encryption Is used […]

The study of secrecy is often associated with cryptography, but nowadays it primarily centers on encryption. Encryption refers to the conversion of plain text into cryptic text as a means of safeguarding against unauthorized access. This process also encompasses decrypting the cryptic text in order to make it comprehensible at the receiving end. Figure 1 […]

The main goal of network security is to protect network resources from unauthorized access, damage, and modification. Cryptography and encryption are essential in ensuring network security. As a network security manager, my responsibilities include researching and evaluating various cryptographic schemes and assessing the security of web systems and wireless networks. Security is crucial in wireless […]

Today, security is an issue concern by everyone. Many ways of implementing encryption algorithms have been investigated in order to achieve better performance in terms of security level, speed, power consumption and cost. This project will discuss about implementing Tiny Encryption Algorithm (TEA) using Field Programmable Gate Array (FPGA). FPGA are reconfigurable chips that the […]

Introduction: Cryptography involves writing messages in code or cipher to secure the content of a text. The encrypted message can only be deciphered using the key used for encoding. It does not hide the existence of the message, but conceals its content [1]. On the other hand, cryptanalysis aims to retrieve the plaintext from a […]

Recently, numerous novel algorithms have been proposed in the fields of steganography and visual cryptography with the goals of improving security, reliability, and efficiency. This paper discusses and compares the two methodologies. Some similarities and differences are presented, in addition to discussing some of the best known algorithms for each. Lastly, an idea for a […]

Abstract The Internet was initially created as a research initiative by the US military to connect US universities and research centers. Internet usage has grown worldwide, with 3.17 billion users (Privgcca, 2016), enabling easier communication via chat, email, and online transactions (Friedman, 2014). The Internet has also enhanced customer service, reduced paperwork, boosted productivity, and […]

The initial forms of data hiding can truly be considered to be extremely simple forms of private key cryptography, the “key” in this case being the information of the scheme being implemented. Steganography books are overflowing with examples of such schemes used all through history. Greek messengers had messages written into their shaved heads, hiding […]
