Abstract:Securityis an important part of computer science that deals with the protection of important information from access, change or modified, and delete, so there are many ways to improve the security of information like cryptography, steganography, biometrics, passwords, barcode..... Howevermostof these methods are consideredkeysrequired.These keys are used toimplement the changing of the information forsecure stylepurpose. For that reason, generating and keeping thesekeys isa major part of theappropriate securitysystem. Moreover, sending the key to the wanted person in unsacred channelis a widelyweakness part forany system. The proposed systemis a novel methodfor generating asecret unique key from an image. A generating process is appliedby discovering the essential colors in the image and constructing a table values for these essential colors , after that asuitable thresholdis usedto considered thesevalues are(0, 1)bitswhich will be used as stream bits key
