Methods of Data Encryption for Use in Safe Space Information

Abstract

The security in the transfer of Raster-type image data using different open computer networks has been extended in recent years, in order to avoid alterations of the information it is necessary to use different encryption methods of the Pixelated data. In order to carry out this purpose, it is required at least to fulfill two objectives in the encryption of Images; the first is to eliminate the correlation between neighboring pixels that have a high similarity and the second is to encrypt the result obtained. The encryption methods of conventional text formats cannot be applied to Raster data, that is why different methods of encryption have been developed, where transformation methods and Chaos theory are used which, due to their high mathematical complexity, allow us to obtain high security encryption. According to the above, the spatial databases require security mechanisms, access control and encryption to guarantee the integrity of the information, therefore there are several types of procedures and techniques oriented to encryption and the security of the databases. Data; some of them will be presented in this article in order to open a new specific field of work in this important area of knowledge.
