QR Codes are used as information channel on several cryptographic architectures due to their technical properties, such as data capacity and retrieval reliability. This paper presents a novel string data validation system using QR Codes and meaningless reversible degradation. The proposed scheme exploits reversible degradation properties, using the systematic Berlekamp Reed-Solomon error correction algorithm and the QR Code. This new mechanism encodes up to 388 characters in two information channels: a dynamic version QR Code (channel 1) and a wireless network (channel 2). A byte mode QR Code stores partial corrupted and masked data input bits. Its version size varies between 1 and 11 according the stored data quantity. The wireless channel downloads a previous generated Reed-Solomon redundancy file to correct the QR Code retrieved information and decode the secret message. The QR Code information is meaningless when scanned by a standard QR Code reader. Compared to real-time retransmission data validation systems, the proposed scheme reduces the download data (channel 2) up to 50%.

“…The use of QR codes in information security has been proposed for a variety of different purposes, such as for authenticating visual cryptography shares [22], e-voting authentication [23], digital watermarking [24], data hiding [7] and secret sharing [10,12,13]. This section presents several studies that are related to the work in this paper.…”

Cooperative Secret Sharing Using QR Codes and Symmetric Keys

Secret sharing is an information security technique where a dealer divides a secret into a collection of shares and distributes these to members of a group. The secret will only be revealed when a predefined number of group members cooperate to recover the secret. The purpose of this study is to investigate a method of distributing shares by embedding them into cover Quick Response (QR) codes in a secure manner using cryptographic keys. The advantage of this approach is that the shares can be disseminated over public channels, as anyone who scans the QR codes will only obtain public information. Only authorized individuals who are in possession of the required keys will be able to recover the shares. This also means that when group members cooperate to recover a secret, the group can determine the presence of an illegitimate participant if the person does not produce a valid share. This study proposes a protocol for accomplishing this and discusses the underlying security of the protocol.

Secret sharing is an effective way of protecting secret messages. However, the traditional secret sharing schemes are considered meaningless due to malicious people attention which might raise risks. To overcome the weakness, this paper presents an effective secret sharing scheme with the functionality of cheater identification, based on meaningful QR code. The secret message will be split and concealed in the padding region of cover QR codes with the assistance of Latin square and it can be completely restored when all the involved participants cooperate. The concealing strategy exploits the characteristic of Reed-Solomon (RS) code to ensure the strong robustness of generated QR code pseudo-shares. The meaningful QR code pseudo-shares help to reduce the curious of unrelated persons. Some experiments were done to evaluate the performance of proposed scheme. The results showed that the proposed scheme is feasible, efficient and secure compared to the other existing schemes. It also achieves a higher secret payload and maintains stronger robustness.
