Image Processing Integrates with Blockchain Technology for Security

    Image processing is an area in which blockchain joins in order to assure security. In common, an image can be of two or three dimensional which can have many useful and sensitive info. In recent days the authentication of large scale system is of by biometric fingerprint that is in image format. For this, blockchain is a promising solution to solve security issue. Hereby we give you key benefits in this area,  

How come Blockchain is useful in image processing?

• It assures security for high-dimensional images
• It is not able to alter are morph the image
• It enables to access remote, since blockchain is not central
• It allows user who have rights to access

    However, there are advantages in blockchain it needs to be present at wherever it is essential. To be specific, the image processing is that nowadays different image based constraints are in use to detect the originality of a user. At present, the security credentials that are in the image format are as below.

Security Credentials in JPEG / PNG format

• Bar code
• QR code
• Fingerprint and also Iris
• Face image

  In simple, an image composes of set of pixels using which the intensity of colours differs. From the pixel values it is possible to build an image, so the pixels are vital in blockchain for storage and verification. As per the general working of blockchain, each block consists of a hash value using which validation is applicable. Just have a look below, to know the basics in a block.

  Block n ::

   {

      <Block_ID>                 // Denotes the identity of the block which is unique

      <Timestamp>             // Defines the creation of this particular block

      <Merkle_root>           // Root hash present in the tree

      <Verifier_ID>            // Denotes the Miner identity who verifies the hash values

      <Nonce_value>         // Numerical value

       <Previous_Hash>    // Denotes the hash value of block (n-1) for the image pixels

        <Hash_n>             // Defines the hash value of block (n)

     }

      From the above syntax, you can find little clear about blockchain. In this way the block of chain forms and allows multiple users. Since the images are larger in size, you can prefer lightweight hashing to hash the values. Our suggestion is that, if your area is image processing, then you can include blockchain which invites in the PhD research society.
