Patent ID: 7302529

Claim:
A method for comparing contents of physical memory components comprised by a first and a second electronic device, the electronic devices being configured to establish a data transmission connection between each other, comprising: determining first checksum values relating to a first data transmission event and second checksum values relating to a second data transmission event, wherein the contents of the first and the second checksum values are derived from or they describe the contents of the physical memory components; transmitting from the first electronic device to the second electronic device where at least one of the first and second electronic devices is a mobile device, an initialization message comprising at least the first checksum value and the second checksum value or information for determining them; and comparing the first checksum values and the second checksum values with each other, as a result of which: the contents of the physical memory components are caused to correspond to each other as a response to the first checksum values or the second checksum values not corresponding to each other.
