Quick Response Code

Abstract: The quick response code (QR) has become most popular barcode because of its larger data capacity and increased damage resistance. Barcode scanners can easily extract information hidden in the QR code when scanning data forms. However, some confidential data stored directly in QR codes are not secure in real world QR apps. To proposed approach to visual secret sharing scheme to encode a secret QR code into distinct shares. In assessment with other techniques, the shares in proposed scheme are valid QR codes that may be decoded with some unique that means of a trendy QR code reader, so that escaping increases suspicious attackers. An existing sharing technique is subjected to loss of security. On this premise, consider the strategy for (k, n) get to structures by using the (k, k) sharing occurrence on each k-member subset dependent on specific relationship. In addition, the secret message is recovered with the aid of XOR-ing the qualified shares. This operation which can effortlessly be achieved the use of smartphones or different QR scanning gadgets. Contribution work is, working on optimal partitioning methods and compare original message with shared message using hashing techniques. Keywords: Hashing, partitioning algorithm, error correction capacity, high security, Quick Response code, visual secret sharing scheme

Private Data

QR code is a quick response code which is used to store information. In QR code, the information is stored in encoded form. To access information present in QR code , we need to decode information with the help of scanner. The information which is present in QR code is accessible to anybody. Private data is not safe in such scenario. This paper presents a visual secret sharing scheme to encode a secret QR code into distinct shares. Visual secret sharing scheme is a method of distributing secrete amongst a group of participants. The secret message is recovered by XOR-ing the shares. Secret message can be generated only when enough number of shares are combined. This provides security for private message using visual secret sharing scheme. Proposed system provides higher security to messages and it also provides more flexible access structure. Computational cost of proposed scheme is low

Error Correction Mechanism

In this paper, a novel visual secret sharing (VSS) scheme using QR codes is investigated. The proposed visual secret sharing scheme based on QR codes(VSSQR) can visually reveal secret image by stacking sufficient (shadow images) shares as well as scan the QR code by a QR code reader. Our VSSQR exploits the error correction mechanism in the QR code structure, to embed the bits corresponding to shares generated by VSS from a secret bit into the same locations of QR codes in the processing of encoding QR. Each output share is a valid QR code, which may reduce the likelihood of attracting the attention of potential attackers. The secret image can be recovered by stacking sufficient QR code shares based on the human visual system without any computation. In addition, it can assist alignment for VSS recovery. The experiment results show the effectiveness of our scheme.
