Data security is a type protecting the stored digital information. It also protects data from corruption. It is used in order to escape from the unauthorized users accessing in computers, internet websites as well as in databases of data. cryptography is a method used to encrypt and decrypt the data. A technique encryption (hiding information) data will be encoded which is used to provide secure data to prevent from fraud user and hackers where decryption is used to convert the encoded data into user readable format. It is also used for storage and transmission compression is a reduction in the number of bits needed to represent data. In this paper cryptography algorithm is user for the purpose of securing the data. It flows from compressing the data first by compression and encryption technique. When these two techniques are done at the same time data can transfer with high speed and takes less time for accessing and also for storage space.
