Abstract

Systems and/or processes related but not limited to a machine configured to create a physical reality of receiving a level-one encrypted output of a surveillance device; a machine configured to create a physical reality of decrypting at least a part of the level-one encrypted output of the surveillance device with a level-one decryption key that is practicably inaccessible by a level-one encryption entity; and a machine configured to create a physical reality of transmitting a plaintext output of the surveillance device. Other machines/processes are also disclosed/claimed.

Claims

1. A method comprising:

receiving a level-one encrypted output of a surveillance device;

decrypting at least a part of the level-one encrypted output of the surveillance device with a level-one decryption key that is practicably inaccessible by a level-one encryption entity associated with the level-one encryption of the output of the surveillance device; and

transmitting a plaintext output of the surveillance device, the transmitting the plaintext output of the surveillance device in conjunction with a surveillance device identifier, and the transmitting the plaintext output of the surveillance device in conjunction with an encrypted version of the surveillance device identifier, wherein the transmitting the plaintext output of the surveillance device in conjunction with the encrypted version of the surveillance device identifier includes;

receiving an encryption of at least a part of a version of the surveillance device identifier that was encrypted with a name-obscuring encryption key whose decryption key is inaccessible by the level-one encryption entity, the name-obscuring encryption key being a different encryption key from a level-one encryption key used to encrypt the output of the surveillance device in order to generate the level-one encrypted output of the surveillance device; and

transmitting the encryption of at least the part of the version of the surveillance device identifier in conjunction with the plaintext output of the surveillance device to name de-obscuring circuitry.

2. The method of claim 1, wherein receiving a level-one encrypted output of a surveillance device comprises:

accepting an output of level-two decryption circuitry.

3. The method of claim 1, wherein receiving a level-one encrypted output of a surveillance device comprises:

accepting a level-one encrypted version of an output of at least one of an image surveillance device, an audio surveillance device, a motion surveillance device, or a tactile surveillance device.

4. The method of claim 1, wherein receiving a level-one encrypted output of a surveillance device comprises:

accepting the level-one encrypted output of the surveillance device in a form such that the level-one encrypted output of the surveillance device is substantially unusable absent combination with other information not present in the level-one encrypted output of the surveillance device.

5. The method of claim 4, wherein accepting the level-one encrypted output of the surveillance device in a form such that the level-one encrypted output of the surveillance device is substantially unusable absent combination with other information not present in the level-one encrypted output of the surveillance device comprises:

accepting an output of level-two encryption circuitry, the output associated with a level-one encryption which cannot practicably be decrypted by a level-one encryption entity.

6. The method of claim 5, wherein accepting an output of level-two encryption circuitry, the output associated with a level-one encryption which cannot practicably be decrypted by a level-one encryption entity comprises:

accepting an output of level-two encryption circuitry, the output associated with a level-one key-pair generation entity.

7. The method of claim 6, wherein accepting an output of level-two encryption circuitry, the output associated with a level-one key-pair generation entity comprises:

accepting an output of level-two encryption circuitry, the output associated with a decryption key generated by a level-one key-pair generation entity.

8. The method of claim 6, wherein accepting an output of level-two encryption circuitry, the output associated with a level-one key-pair generation entity comprises:

accepting an output of level-two encryption circuitry, the output associated with a key-pair designator generated by a level-one key-pair generation entity.

9. The method of claim 1, wherein decrypting at least a part of the level-one encrypted output of the surveillance device with a level-one decryption key that is practicably inaccessible by a level-one encryption entity associated with the level-one encryption of the output of the surveillance device comprises:

receiving the level-one decryption key inaccessible by a level-one encryption entity from a level-one key-pair generation entity.

10. The method of claim 9, wherein receiving the level-one decryption key inaccessible by a level-one encryption entity from a level-one key-pair generation entity comprises:

receiving a level-one key pair designator from a level-one key-pair generation entity in a form of a level-one decryption key that may thereafter function as the level-one key-pair designator.

12. The method of claim 1, wherein decrypting at least a part of the level-one encrypted output of the surveillance device with a level-one decryption key that is practicably inaccessible by a level-one encryption entity associated with the level-one encryption of the output of the surveillance device comprises:

decrypting at least a part of a level-one encrypted output of the surveillance device via combination with other information not present in the level-one encrypted output of the surveillance device.

13. The method of claim 12, wherein decrypting at least a part of a level-one encrypted output of the surveillance device via combination with other information not present in the level-one encrypted output of the surveillance device comprises:

receiving a level-one decryption key inaccessible by the level-one encryption entity from a level-one key-pair generation entity.
