Abstract

Mechanisms are provided to sequence one or more access control keys residing on a mobile device to be used with an access control reader. In particular, solutions are described which allow a mobile device to receive one or more access control keys and receive additional sequence data. The sequence data may be created for a particular route or course such that a user is require to present the received access control keys to an access control reader in a particular order to gain access to a protected asset.

First claim

What is claimed is:

1 . A method for managing a sequence of access control keys comprising:
receiving one or more access control keys at a mobile device; determining whether or not the one or more received access control keys are valid; and presenting at least one valid access control key to an access control reader.

2 . The method for managing access control keys of claim 1 , further comprising:
receiving, at the mobile device, sequence data associated with the one or more access control keys.

3 . The method for managing access control keys of claim 1 , further comprising:
receiving, at the mobile device, sequence data associated with the one or more access control keys, wherein one or more received access control keys are determined to be valid based on a use of a previously presented access control key designated by the received sequence data.

4 . The method for managing access control keys of claim 1 , further comprising:
receiving, at a mobile device, sequence data associated with the one or more access control keys; ordering the one or more received access control keys based upon the received sequence data; and selecting at least one access control key to determine whether or not at least one access control key is valid.

5 . The method for managing access control keys of claim 4 , wherein the at least one selected access control key corresponds to a route a user is to follow.

6 . The method for managing access control keys of claim 4 , wherein the one or more received access control keys are determined to be valid based on a use of a previously presented access control key designated by the received sequence data.

7 . The method for managing access control keys of claim 1 , wherein the one or more access control keys are received in an order in which the one or more access control keys are to be presented to an access control reader.

8 . The method for managing access control keys of claim 1 , wherein at least one of the one or more received access control keys update an access control key already residing on the mobile device.

9 . The method for managing access control keys of claim 2 , wherein the received sequence data alters an access control key to which the received one or more access control keys depend.

10 . The method for management access control keys of claim 2 , wherein the sequence data further includes additional criteria for determining whether the one or more received access control keys are valid.

11 . The method for managing access control keys of claim 10 , wherein the one or more received access control keys may be determined to be valid based upon the mobile device having passed within a predetermined distance of one or more locations.

12 . The method for managing access control keys of claim 10 , wherein the one or more received access control keys may be determined to be valid based upon a schedule.

13 . A non-transitory computer readable medium with instructions stored thereon that when executed by a processor performs the method of claim 1 .

14 . An access key control system, comprising:
one or more mobile devices comprising:
a wireless communication module;
a memory configured to store one or more access control keys, wherein the one or more access control keys are received via the wireless communication module;
a memory configured to store a key management module, wherein the key management module is configured to manage one or more access control keys;
a processor operatively connected to the mobile device, wherein the processor is configured to execute the key management module; and
one or more mobile key servers, wherein the mobile key server is operative to provide one or more access control keys to the one or more mobile devices; and wherein one or more access control keys are presented to an access control reader to gain access to a protected asset.

15 . The access key control system of claim 14 , wherein the memory is further configured to store a sequence data module, wherein the sequence data module receives sequence data from the one or more key servers; the sequence data being associated with the one or more access control keys, wherein one or more of the stored access control keys are determined to be valid based on a use of a previously presented access control key designated by the stored sequence data.

16 . The access key control system of claim 15 , wherein the key management module orders the one or more provided access control keys based upon the stored sequence data, and wherein the key management module selects at least one access control key to determine whether or not the at least one access control key is valid.

17 . The access key control system of claim 16 , wherein the at least one selected access control key corresponds to a route a user is to follow.

18 . The access key control system of claim 14 , wherein the one or more access control keys are provided in an order in which the one or more access control keys are to be presented to an access control reader.

19 . The access key control system of claim 15 , wherein at least one of the one or more provided access control keys update an access control key already stored in the memory.

20 . The access key control system of claim 15 , wherein the provided sequence data alters an access control key to which the provided one or more access control keys depend.
