The lecturer, Prof. Dr. Alaa Kazem Farhan, from the Computer Science Department at the University of Technology, has published two papers in an international scientific journal A court that is classified within the Clarfit database and at the first quarter level (q1) and has a high impact factor (IF) as this journal is one of the journals Global discreet and does not accept research of scientific originality. The first research titled "New improvement with active expansion to improve MD5 hash function for verifying secure electronic document" which summarizes His idea is to enhance the MD5 algorithm by adding dynamic variable length and efficiency High simulates the highest levels of safety available while a logistic system is used to encode DNA (RNA) by creation A random array based on a new key created using different techniques. As for the second research entitled "Improving the capability of the QR code by means of encrypted compression technology without losing data from the document." The proposed algorithm includes a clear and simple plan to overcome this difficulty by entering confidential information In a message QR code, the QR code is updated by adding levels that help to share secure messages Different sizes and documents validation for verification and validation.
