Protocol for program during startup sequence
View Patent ↗A system and a method to determine if a client (e.g., an accessory (or peripheral)) is appropriately licensed for interoperation with a host (e.g., host computer). The client communicatively couples the host and receives a contract from the host. The client computes a checksum of the contract and compares the checksum of the contract with a previously stored version of the contract or a checksum of the contract to determine a match. If there is no match, the host communicatively decouples the client in response to the determination being a no match. If there is a match, the client transmits a contract response to the host and awaits host authorization. Once authorized the client transmits enumeration data to the host.
1. A computer-implemented method for permitting authorization of a client device with a host device, the method comprising:
receiving an indication of communicatively coupling with the host device;
transmitting an agreement file to the client device, the agreement file corresponding to a pre-negotiated agreement;
receiving from the client device a response file in response to the transmitted agreement file;
comparing the response file with a pre-stored version of the response file;
authorizing, in response to a match between the response file and the pre-stored version of the response file, access for the client device; and
receiving, from the client device, enumeration data.
2. The method of claim 1 , wherein comparing further comprises computing a checksum of the response file and comparing it with a pre-stored version of a checksum of the response file to determine a match.
3. The method of claim 1 , wherein comparing further comprises comparing characters of the agreement file with characters in the response file to determine a match.
4. The method of claim 1 , further comprising at least one of:
communicatively decoupling from the host device in response to the determination being a no match, and
granting access to the host device for a predetermined period of time in response to the determination being a no match.
5. The method of claim 1 , wherein the agreement file comprises a legal agreement text.
6. The method of claim 5 , wherein the response file comprises a legal response text.
7. The method of claim 1 , wherein the client device comprises an accessory and the host device comprises a computing device.
8. The method of claim 4 , wherein the accessory comprises one of a physical accessory or a logical accessory.
