Blockchain systems and methods for confirming presence
Systems and methods for confirming the presence of a person or asset for a given purpose, and recording this information in a distributed ledger. The distributed ledger records and confirms presence indicia in connection with a transaction said facilitates remote and/or automated signatures. The systems and methods detect the presence of one or more humans and/or computing devices at a specific location at the time of a transaction, and contemporaneously recording information concerning the transaction in a distributed ledger. Presence can be determined using network presence sensing (NPS), other types of sensors, or the combination of NPS with other sensors.
1. A method for documenting the presence of a human and computing device together at a particular place and time comprising:
providing a first set of one or more sensors disposed at a location;
providing a second set of one or more sensors also disposed at said location;
providing a distributed ledger adapted to record timestamped records;
detecting, using said first set of one or more sensors, a human present at said location at a time;
detecting, using said second set of one or more sensors, a computing device also present at said location at said time;
because said human was detected by said first set of sensors and said computing device was detected by said second set of sensors, posting to said distributed ledger a timestamped record indicating both said detected presence of said human and said detected presence of said computing device at said location and at said time.
2. The method of claim 1 , wherein said first set of one or more sensors comprises a network presence sensing system.
3. The method of claim 1 , wherein at least one sensor in said fast set of one or more sensors comprises a motion sensor.
4. The method of claim 3 , wherein said motion is selected from the group consisting of: a passive infrared sensor, an ultrasound sensor, and a hybrid system.
5. The method of claim 1 , wherein at least one sensor in said first set of one or more sensors is selected from the group consisting of: a beam break sensor, a camera, and a weight plate.
6. The method of claim 1 , wherein at least one sensor in said first set of one or more sensors is selected from the group consisting of: a transceiver, a camera, and a microphone.
7. The method of claim 6 , wherein said at least one sensor comprises a transceiver adapted for wireless communicates using radio waves.
8. The method of claim 1 , wherein said posted timestamped record includes additional information.
9. The method of claim 8 , wherein said additional information is in a raw or a processed form.
10. The method of claim 8 , wherein said additional information includes one or more of the group consisting of: video information audio information; a state of an access point to said location; a security system status; a weight sensor status; current weather; predicted weather; photographs; and light sensor information.
