Dynamic verification of application data using deterministic functions

摘要

A client can request, from a server, files needed to run a web application at the client (e.g., via a client web browser). The server can serve the requested files to the client along with a file identifier for each of the files. The file identifier for a respective file can be generated dynamically based on the contents of the respective file. When the requested files and the file identifiers are received at the client, the client can dynamically generate a validation code based on the file identifiers. Similarly, at the server, a verification code can be generated dynamically based on the file identifiers transmitted. To verify that the client has the appropriate files for running the web application, the server can compare the validation and verification codes. If the two codes match, then it can be verified that the client has the appropriate files for the web application.
