Abstract

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.

Claims

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.
