Abstract

Technologies are generally described for providing an encryption method using real-world objects. In some examples, a method may include capturing, by a first electronic device, an external object, generating an object signal associated with the external object, generating an encryption key based on the object signal, and transmitting data encrypted by the encryption key to a second electronic device.

First claim

What is claimed is:

1. A method, comprising:
generating, by a system comprising a hardware processor, a signal based on information associated with an image;
determining by the system, a characteristic vector value corresponding to the signal;
transmitting, by the system, a normalization parameter for the signal associated with the image to a device; and
generating, by the system, an encryption key based on quantization information comprising at least one quantization pattern that is associated with the normalization parameter and is received by the device, the generating comprising comparing the characteristic vector value to a set of sample characteristic vector values associated with a set of vector-key pairs for a set of sample images.

2. The method of claim 1 , further comprising:
quantizing by the system, the signal to generate a quantization pattern associated with the information.

3. The method of claim 2 , wherein the generating the encryption key comprises generating the encryption key based on comparing the quantization pattern to another quantization pattern associated with the image.

4. The method of claim 1 , further comprising:
searching, by the system, a data storage that stores of vector-key pairs, the set of vector-key pairs comprising the set of sample characteristic vector values and a set of keys associated with the set of sample characteristic vector values.

5. The method of claim 1 , further comprising:
capturing, by the system, the information associated with the image.

6. The method of claim 1 , further comprising:
transmitting, by the system, data encrypted by the encryption key to the device.

7. The method of claim 6 , further comprising:
storing, by the system, the encryption key in association with an identifier of the device.

8. A system, comprising:
a memory that stores computer-executable components; and
a hardware processor, communicatively coupled to the memory, that executes or facilitates execution of the computer-executable components, the computer-executable components comprising:
a capture component configured to capture information associated with an image;
a characteristic extraction component configured to determine a characteristic vector value associated with the information;
a transceiver component configured to transmit a normalization parameter for the information associated with the image to a device; and
a key generation component configured to generate an encryption key based on a quantization pattern that is associated with the normalization parameter and is received by the device and a comparison between the characteristic vector value and a set of sample characteristic vector values associated with a set of vector-key pairs for a set of images associated with a data storage.

9. The system of claim 8 , wherein the computer-executable components further comprise:
a quantization component configured to quantize the information to generate another quantization pattern.

10. The system of claim 9 , wherein the key generation component is further configured to generate the encryption key based on another comparison between the quantization pattern and the other quantization pattern.

11. The system of claim 8 , wherein the key generation component is further configured to search the data storage or another data storage that stores the set of vector-key pairs, and wherein a vector-key pair from the set of vector-key pairs comprise a sample characteristic vector value and a key associated with the sample characteristic vector value.

12. The system of claim 8 , wherein the transceiver component is configured to transmit data encrypted by the encryption key to the device, wherein the device provides another encryption key based on other information associated with the image.

13. The system of claim 12 , wherein the computer-executable components further comprise:
a storage component configured to store the encryption key in association with an identifier of the device.

14. A computer-readable storage device comprising computer-executable instructions that, in response to execution, cause a device comprising a processor to perform operations, comprising:
generating information associated with an image;
extracting a characteristic vector value corresponding to the information;
transmitting a normalization parameter for the information associated with the image to a computing device; and
generating an encryption key based on a quantization pattern that is associated with the normalization parameter and is received by the computer device, and similarities between the characteristic vector value and a set of sample characteristic vector values associated with a set of vector-key pairs for a set of other images.

15. The computer-readable storage device of claim 14 , wherein the operations further comprise:
searching a data structure that stores the set of vector-key pairs, a vector-key from the set of vector-key pairs comprising a sample characteristic vector value and a key associated with the sample characteristic vector value.

16. The computer-readable storage device of claim 14 , wherein the generating the encryption key comprises generating the encryption key based on the quantization pattern.

17. The computer-readable storage device of claim 16 , wherein the generating the encryption key comprises comparing the quantization pattern and another quantization pattern associated with the image.
