Abstract

A method for providing data on the Internet, comprising calculating, using a microprocessor, a value of a predetermined function for said data, wherein the value depends on the data, determining, using said microprocessor, a uniform resource identifier including said value, and storing, at a resource on the Internet, said data, wherein the resource is accessible by using the uniform resource identifier. Further, a method for accessing data on the Internet is provided, comprising retrieving said data from a resource in the Internet by using a uniform resource identifier, determining, using a microprocessor, a part of the uniform resource identifier, the part corresponding to a value of a predetermined function, calculating, using the microprocessor, a further value for said data based on said predetermined function, wherein the value depends on the data, and determining, using the microprocessor, the integrity of said data by comparing said value and said further value.
