Abstract

Method and devices for making access decisions in a secure access network are provided. The access decisions are made by one or more portable credentials using data and algorithms stored on or received by two or more credentials. Since access decisions are made by the portable credential or credentials, non-networked hosts or local hosts can be employed that do not necessarily need to be connected to a central access controller or database, thereby reducing the cost of building and maintaining the secure access network.

First claim

What is claimed is:

1 . A method, comprising:
presenting a first and a second credential to a reader, said reader associated with an access control system; said reader transmitting data comprising at least one of a host identifier and timestamp to said first and second credentials; said first credential receiving information from said second credential; said first credential analyzing the at least one of a host identifier and timestamp using an application stored on said first credential and further analyzing said information from said second credential, said first credential making an access control decision, the access control decision comprising a determination as to whether or not the first and second credentials are both allowed access to an asset protected by said reader, and the access control decision being based on said analyzing step; said first credential generating a first message containing results of said access control decision; and said first credential sending said first message to said reader.

2 . The method of claim 1 , wherein said information from said second credential corresponds to at least one of a PIN, a password, biometric identification information, a user selection, and information gathered from one or more sensors on the second credential.

3 . The method of claim 1 , further comprising:
said reader transmitting results of said access control decision to an access controller.

4 . The method of claim 3 , wherein said access controller comprises at least one of a lock for an individual door, a lock for a computer system, a lock for a computer, and a lock for a database.

5 . The method of claim 3 , wherein said access control decision comprises a grant of access to an asset associated with said access control system, the method further comprising:
said access controller granting a user of said first and second credentials access to said asset; and said reader saving said first message received from said first credential in a log.

6 . The method of claim 3 , wherein said access control decision comprises a denial of access to an asset associated with said access control system, the method further comprising:
said access controller denying a user of said first and second credentials access to said asset; and said reader saving said first message received from said first credential in a log.

7 . The method of claim 1 , wherein said first message is encrypted prior to being sent from said first credential to said reader.

8 . The method of claim 1 , wherein the information received from said second credential is at least one of a control key, a control or access schedule, and an expiration time.

9 . The method of claim 1 , further comprising:
said second credential analyzing the at least one of a host identifier and timestamp using an application stored on said second credential, said second credential making a second access control decision, the second access control decision comprising a determination as to whether or not the second credential is allowed access to an asset protected by said reader, and the second access control decision being based on said analyzing step; said second credential generating a second message containing results of said second access control decision; and said second credential sending said second message to said first credential.

10 . The method of claim 9 , wherein the information received from said second credential comprises the second message.

11 . The method of claim 9 , further comprising:
said second credential receiving from said first credential at least one of a control key, a control or access schedule, and an expiration time.

12 . The method of claim 1 , wherein said reader is a non-networked reader.

13 . The method of claim 1 , further comprising performing authentication between said reader and said first credential and between said reader and said second credential prior to said reader transmitting data to said first and second credentials.

14 . The method of claim 1 , wherein at least one of the first credential and the second credential is a wearable computer.

15 . An access control system, comprising:
at least one local host for controlling access to an asset; and at least two credentials, each credential comprising:
a memory for storing an access decision application that is capable of making an access decision for said credential based on data received from the at least one local host, the access decision comprising a determination as to whether or not the credential is allowed access to the asset protected by said at least one local host; and
a processor for executing said access decision application in connection with said received data, wherein said processor is further capable of generating a message after executing said access decision application and causing said message to be transmitted to one of the other credential and the at least one local host, and wherein said message comprises results of said access decision for said credential.

16 . The system of claim 15 , wherein said received data comprises at least one of a local host identifier assigned to the at least one local host, authentication information, and a timestamp.

17 . The system of claim 15 , wherein the at least one local host comprises:
a reader for communicating with the at least two credentials; and an access control device in communication with said reader, wherein matching results of said access decisions received at said reader are transmitted to said access control device for performance by the access control device consistent with said access decisions.

18 . The system of claim 15 , wherein at least one of the at least two credentials comprises a contact smartcard, a contactless smartcard, a proximity card, a passport, a key fob, a cellular phone, a portable computer, or a Personal Digital Assistant (PDA).

19 . A credential for use in a secure access system, comprising:
a memory for storing an access decision application that is capable of making an access decision for said credential based on data received from a local host and data received from a second credential, the access decision comprising a determination as to whether or not the credential and the second credential are allowed access to an asset protected by the local host; and a processor for executing said access decision application in connection with said received data, wherein said processor is further capable of generating a message after executing said access decision application and causing said message to be transmitted to the local host, and wherein said message comprises results of said access decision for said credential.

20 . The credential of claim 19 , wherein said data received from a second credential comprises at least one of a control or access schedule, a control key, an expiration time, a PIN, a password, biometric identification information, an indication of whether the second credential is allowed access to the asset protected by the local host, and an indication of whether the second credential has completed one or more steps required to be completed by the second credential for the access decision application to determine that the credential is allowed access to the asset.
