Systems and methods for secure access to property or information using blockchain

Abstract

Blockchain-based systems and methods are used to control access to property or information. One system includes a mobile device or other smart device, a key fob or other e-key object, and a server. The mobile device generates an encrypted code and transmits it to the key fob. The key fob transmits the encrypted code to the property and the server updates a log in a hyperledger. The property includes a computing device that validates the encrypted code and grants a key fob user access to the property. Another system includes a server that validates an access key and a first station that transmits an access key to a second station via the server and a satellite. The second station transmits data to the first station via the server and the satellite. The server saves a transmission log in a hyperledger and transmits the access key in response to a request.

1 . An e-key system comprising:
 a mobile device configured to generate an encrypted code;   a key fob configured to receive the encrypted code from the mobile device and to transmit the encrypted code to a computing device incorporated into property via wireless communication; and   a server configured to update an access log of the key fob in a hyperledger,   wherein the computing device includes a validation module configured to validate the received encrypted code, and   wherein the computing device grants a user of the key fob access to the property when the validation module validates the encrypted code.   
     
     
         2 . The e-key system according to  claim 1 , wherein the wireless communication is Bluetooth communication. 
     
     
         3 . The e-key system according to  claim 1 , wherein the mobile device and the key fob are paired according to a Bluetooth protocol. 
     
     
         4 . The e-key system according to  claim 1 , wherein the computing device of the property and the key fob are paired according to a Bluetooth protocol. 
     
     
         5 . The e-key system according to  claim 1 , wherein the validation module is constantly powered by the property. 
     
     
         6 . The e-key system according to  claim 5 , wherein the validation module is an electronic circuit. 
     
     
         7 . The e-key system according to  claim 1 , wherein the code is encrypted with a public key by the mobile device. 
     
     
         8 . The e-key system according to  claim 7 , wherein the validation module decrypts the encrypted code with a private key, which is saved in the validation module, corresponding to the public key. 
     
     
         9 . The e-key system according to  claim 1 , wherein the validation module transmits the access log to the server when a network connection is established with the server. 
     
     
         10 . The e-key system according to  claim 1 , wherein the property is an aircraft, watercraft, hovering vehicle, land vehicle, or building. 
     
     
         11 . A method for granting access to property to a user of a key fob, the method comprising:
 transmitting, by a mobile device, an encrypted code to a key fob;   transmitting, by the key fob, the encrypted code to a validation module running on a computing device of property via wireless communication;   determining, by the validation module, whether the encrypted code is valid;   granting access to the property when it is determined that the encrypted code is valid; and   denying access to the property when it is determined that the encrypted code is invalid.   
     
     
         12 . The method according to  claim 11 , wherein the wireless communication is Bluetooth. 
     
     
         13 . The method according to  claim 11 , wherein the property and the key fob are paired according to a Bluetooth protocol. 
     
     
         14 . The method according to  claim 11 , wherein the mobile device and the key fob are paired according to a Bluetooth protocol. 
     
     
         15 . The method according to  claim 11 , wherein the encrypted code is encrypted by a public key. 
     
     
         16 . The method according to  claim 15 , further comprising decrypting, by the validation module, the encrypted code with a private key, which is saved in the validation module, corresponding to the public key. 
     
     
         17 . The method according to  claim 11 , further comprising transmitting, by the validation module, an access log to a server when a network connection is established with the server. 
     
     
         18 . The method according to  claim 11 , wherein the property is an aircraft, watercraft, hovering vehicle, land vehicle, or building.
