Abstract
The invention is related to the use of one or several digital signatures obtained from at least one structural characteristic of a material element that has a complex, chaotic, unique and stable structure, to protect the direct reading of sensitive data, a media of such protected data and a method for reading this protected data.
Claims56
A method for reading protected sensitive data comprising:
- acquiring one or more complex, chaotic, unique, and stable structural characteristics of one or more material elements selected from the group consisting of a fibrous material, plastic, metal, leather, wood, composite material, glass, mineral, or a crystalline structure;
- digitizing and encoding the acquired one or more structural characteristics;
- generating one or more digital signatures of the encoded and digitized one or more structural characteristics;
- decrypting, by a processor, at least one or more data using the one or more digital signatures as keys;
- reading the decrypted one or more data.
A method for protecting sensitive data comprising:
- acquiring one or more complex, chaotic, unique, stable, and physical structural characteristics of one or more material elements selected from the group consisting of a fibrous material, plastic, metal, leather, wood, composite material, glass, mineral, and a crystalline structure;
- digitizing and encoding the acquired one or more structural characteristics;
- generating one or more digital signatures of the encoded and digitized one or more structural characteristics;
- encrypting at least one or more data using the one or more digital signatures as keys;
- storing the encrypted one or more data in a computer readable storage device.
A non-transitory computer readable medium containing data protected against direct reading, the data protected by the steps comprising:
- acquiring one or more complex, chaotic, unique, stable, and physical structural characteristics of one or more material elements selected from the group consisting of a fibrous material, plastic, metal, leather, wood, composite material, glass, mineral, and a crystalline structure;
- digitizing and encoding the acquired one or more structural characteristics;
- generating one or more digital signatures of the encoded and digitized one or more structural characteristics;
- encrypting at least one or more data using the one or more digital signatures as keys;
- storing the encrypted one or more data;
- wherein the medium is in a form of a paper, cardboard or nonwoven document
A method for securing sensitive data comprising the following steps:
- a) one step of protecting the direct reading of sensitive data comprising:
- acquiring one or more complex, chaotic, unique, stable, and physical structural characteristics of one or more material elements selected from the group consisting of a fibrous material, plastic, metal, leather, wood, composite material, glass, mineral, and a crystalline structure;
- digitizing and encoding the acquired one or more structural characteristics;
- generating one or more digital signatures of the encoded and digitized one or more structural characteristics;
- encrypting at least one or more data using the one or more digital signatures as keys;
- storing the encrypted one or more data in a non-transitory computer readable medium;
- and
- b) one step of reading the protected sensitive data obtained in step a), thereby allowing finding of the sensitive data.
