Abstract:
Method for generating a compressed file name at a server at session initialization in response to an initial request from a user in anticipation of a subsequent request to use, delete or alter the named file and for responding to said subsequent request, the method comprising the steps of:storing at said server a user attribute, and a hidden key value;communicating said initial request from said user to said server, said initial request including a file name, a user profile and file data;operating said server, responsive to said initial request and without reference to any prompting for user assigned credentials, according to the steps of:building a first input string, said first input string including the user profile from said initial request, said user attribute and said hidden key value;hashing said first input string to generate a first tag;concatenating said first tag with a fixed identifier to generate a first file name for said file data; andstoring said file data identified by said first file name;communicating said subsequent request from said user to said server, said subsequent request including said user profile, said file name, and a file command; andoperating said server at session initialization and without reference to any user prompting, responsive to said subsequent request, according to the steps of:building a second input string, said second input string including the user profile from said subsequent request, said user attribute, and said hidden key;hashing said second input string to generate a second tag;concatenating said second tag with said fixed identifier to generate a second file name;comparing said second file name to said first file name and, if equal, executing said file command with respect to the file identified by said first file name.
