Abstract
A method of securely encrypting data whereby a computing device can utilize a seed and a pin to generate a mantissa of an irrational number. The computing device can then utilize a portion of the mantissa as a one-time pad to encrypt data. The seed can be transmitted to a recipient via a graphical code to enable secure decryption by a recipient's computing device.
Claims19
A method of securing data, comprising:
- using, by a computing device, a seed and a pin to generate a portion of a mantissa of an irrational number;
- using, by the computing device, the portion of the mantissa as a one-time pad;
- encrypting, by the computing device, the data with the one-time pad;
- utilizing, by the computing device, the seed as a first portion of a key;
- utilizing, by the computing device, the pin as at least part of a second portion of the key:,
- generating, by at least one of the computing device or a second computing device, a decryption key from the first potion of the key and the second portion of the key;
- and
- decrypting, by the at least one of the computing device and the second computing device, the data using the decryption key.
