New Technology to enhance data protection - Security QR Code
Due to the raising concern of personal information protection, securing data is strongly needed in the market. Therefore, Denso-Wave Incorporated has developed “Security QR Code (SQRC)” to keep data non-disclosure for unauthorized user.
Lock the Private Data
Only a specific scanner, which is with the same setting of the encryption key that is set with the SQRC is made can read SQRC. SQRC consists of mixed public data and private data (data encryption key). Scanner that supports the SQRC is able to read both the public data (e.g. person’s name) and private data (person’s age, health details and identification number). The security QR code has the same figure as normal QR Code and only the public data can be read as QR Code by a general scanner.

Remarks:
SQRC Encryption Key is of 8 bytes in size. The generator (software) will specify a unique encryption key for each set of SQRC is generated, while the scanner is able to specify max. 8 SQRC read-only encryption key.
