Enkripsi dan Dekripsi Data Menggunakan Garis Telapak Tangan

Abstract

This paper discuss the use of hand lines to encrypt and decrypt the data. Encryption and decryption of data are important in the the world of information technology. Encryption is the process of securing an information with the aim of making the information unreadable or not easily understand without the help of specialized knowledge (the key). Decryption is the process of returning a result of information that had been encrypted with the aim to make the information can be read or understood with the help of specialized knowledge (the key). It s need a unique key to encrypt and decrypt an information. The use of palm lines can serve as a unique key. To make the palms line to be a necessary key, users palms line image needed. The images will be processed and analyzed with edge detection method to determine the pattern of palm lines. Furthermore, the results of the drawing process will be used to make histogram to determine a number or value. The numbers or values can be used as a reference key to encrypt the data using encryption algorithm which has been made.
