This chapter discusses Revelation’s soundscape and meaning as a huge hymn festival around the marriage feast of the Lamb. It is about God’s goodness, mercy, and power over evil in a cosmic view, not a secret code for our calendars. Relationships between the book of Revelation and the church’s liturgy and music are explained, along with influences from the liturgy to Revelation and from Revelation to the liturgy. The Sanctus and Agnus Dei of the Ordinary, hymns, and other music for the worship of the church are included. Oratorios and Olivier Messiaen’s Quartet for the End of Time move to music, which, though outside the liturgy, also relate to Revelation and express its themes. Some implications about Revelation’s relevance for worship, music, and life together conclude the article. In Messiaen’s words, “It is all love.”

Original Information

One of the main methods of security is cryptography encrypting data so that only a person with the right key can decrypt it and make sense of the data. There are many forms of encryption, some more effective than others. Cryptography works by taking the original information and converting it with cipher text, which encrypts the information to an unreadable form. To decrypt the information we simply d the opposite and decipher the unreadable information back into plain text. This enciphering and deciphering of information is done using an algorithm called a cipher. A cipher is basically like a secret code, but the main difference between using a secret code and a cipher is that a secret code will only work at a level of meaning. This chapter discusses a little of the history of cryptography, some popular encryption methods, and also some of the issues regarding encryption, such as government restrictions.

Encryption Method

Some chaos-based image encryption schemes using plain-images independent secret code streams have weak encryption security and are vulnerable to chosen plaintext and chosen cipher-text attacks. This paper proposed a two-level secret key image encryption method, where the first-level secret key is the private symmetric secret key, and the second-level secret key is derived from both the first-level secret key and the plain image by iterating piecewise linear map and Logistic map. Even though the first-level key is identical, the different plain images will produce different second-level secret keys and different secret code streams. The results show that the proposed has high encryption speed, and also can effectively resist chosen/known plaintext attacks.

In this paper, a complete fault-tolerant check recognition system is proposed which has no check substitution error under the secret code verification. The fault-tolerant recognition method proposed in this paper creates all possible candidates for verification under the limited fault-tolerant rate, and with three classifiers of high isolated digit recognition rate, the system can always find out the correct recognition results of checks if there exist the correct labels of all the digits. Since the three classifiers are designed independently by different methods and they extract different features of handwritten digits, they can compensate each other when confusing digits are met. The segmentation stage combines the three most popular strategies, and gives out a way for segmenting unconstrained handwritten numeral strings on Chinese checks.

<div><p>The raise in the recent security incidents of cloud computing and its challenges is to secure the data. To solve this problem, the integration of mobile with cloud computing, Mobile biometric authentication in cloud computing is presented in this paper. To enhance the security, the biometric authentication is being used, since the Mobile cloud computing is popular among the mobile user. This paper examines how the mobile cloud computing (MCC) is used in security issue with finger biometric authentication model. Through this fingerprint biometric, the secret code is generated by entropy value. This enables the person to request for accessing the data in the desk computer. When the person requests the access to the authorized user through Bluetooth in mobile, the Authorized user sends the permit access through fingerprint secret code. Finally this fingerprint is verified with the database in the Desk computer. If it is matched, then the computer can be accessed by the requested person.</p></div>
