SQRC (Secure QR Code) is a new QR code with data reading restriction. Conventional QR code, which can be read commonly with a cell phone, has come in to use for various purposes. However, when a user wants to limit the data reading, complicated process is required such as data encryption before printing and data decryption after reading SQRC is a newly developed 2-D code to solve such problems. It makes it easy to encode and use non-public information including personal information and in-house information by printing QR code with SQRC compatible printer marker and reading it with a special scanner. With the development of SQRC, 2-D code is expected to be applied to new areas.
Difference between SQRC and QR code
- More efficient, more convenient
- QR code has boasted its space-saving feature and high capacity. However, some security concerns remain because any scanner can read the same information; therefore personal information and confidential information can be read through the process.
- SQRC can give specific information to a specific person because readable information can be controlled according to the device used, by changing public/non-public setting for the code information with a cryptography key. In addition, there is no need of encryption and decryption.
