Title: System and method for providing access from a remote location

Description:
BACKGROUND OF THE INVENTION  
       [0001] The present invention relates generally to a system and method for providing access to a locked or otherwise secured area from a remote location. More specifically, an exemplary embodiment of the present invention relates to a system for and method of providing access from a remote location using a communication device by utilizing the communication device to provide access to a stored device that can be used to gain access.  
       [0002] Security and convenience are two of the many motivation factors prompting people to upgrade to ever more sophisticated and elaborate security systems for their homes or buildings. People seek security systems that allow them to maximize the security of the building or other space while also minimizing the inconvenience and cost associated with the additional security.  
       [0003] One way to maximize security is to secure the building using conventional locks, security systems, or other access prevention methods. Locking a building, activating the security system, or generally preventing access may effectively prevent access to everyone who does not have the key configured to allow the holder to bypass whatever access prevention methods are being used.  
       [0004] However, using access prevention methods can effectively deny access to everyone who does not have a key. There may be times when preventing all access to a person is not desirable, but neither is providing a key to that person that would allow continuous access. Examples could includes providing access to a cleaning service, providing access to a visitor when running late for an appointment, providing access to children returning from school, etc.  
       [0005] Present systems exist that provide remote access using a communication device and a control circuit capable of controlling a lock or other prevention method to provide access. However, such systems are generally expensive and require structural modifications to access points to provide the necessary equipment that allows for providing access from a remote location. Further, specialized equipment can be required such as locks capable of being secured or unsecured based upon receipt of a signal.  
       [0006] Thus, there is a need for a system or method for providing access to a remote location using a key or other bypass method. Further, there is a need to provide this system or method in a manner such that access is provided one time based on a communication from a communication device. Further, there is a need to provide this system or method in a manner that does not require retrofitting of the access point. Further, there is a need to provide the system or method in a manner that is cost efficient.  
       SUMMARY OF THE INVENTION  
       [0007] One embodiment of the invention relates to an apparatus for providing access to a secured space from a remote location.

The request can be made by voice communication, alphanumeric communication or any other means that communication an access request from the person seeking entry to the person controlling entry. The request can further be associated with a greater or lesser amount of data. For example the request can include an identity verification, such as an image taken of the person seeking entry, or a biometric input, such as a scan from a fingerprint reader.  
     [0052] The person controlling entry can receive the access request and any associated data in a step  430 . Following receipt of data a determination is made in a step  440  whether access should be granted to the person seeking access. If access is to be denied, the system exits.  
     [0053] If access is to be granted, a step  450  can be performed wherein the person controlling access can send a signal over the communication channel to a box containing an access device. The signal can unlock the box, allowing the person seeking entry to obtain a key that will allow access.  
     [0054] While the exemplary embodiments illustrated in the FIGURES and described above are presently preferred, it should be understood that these embodiments are offered by way of example only. Other embodiments may include, for example using the described system and method to control access to some other defined space, such as a room, a vault, a box, etc. The invention is not limited to a particular embodiment, but extends to various modifications, combinations, and permutations that nevertheless fall within the scope and spirit of the appended claims.
