Naor and Shamir proposed a new dimension of Information security as visual cryptography which is a secret sharing scheme among N number of participants with pixel expansion. Later on, many researchers extended the visual secret sharing scheme with no expansion of pixel regions in binary and color images. By stacking k shares the secret can be decoded using normal vision. In this paper the authors have proposed a modification towards visual cryptography by converting the message in the form of printable ASCII character-based numerical encoding patterns in a binary host image. The encoding of the message is represented as ASCII numeric and a texture of those numeric are arranged to form a binary host image. Then, N numbers of shares are built up but after stacking all the shares the decoding of the message is achieved by converting ASCII numeric to the secret.<\/jats:p>","DOI":"10.4018\/ijrsda.2019010102","type":"journal-article","created":{"date-parts":[[2018,12,12]],"date-time":"2018-12-12T10:34:28Z","timestamp":1544610868000},"page":"18-42","source":"Crossref","is-referenced-by-count":0,"title":["A New Bi-Level Encoding and Decoding Scheme for Pixel Expansion Based Visual Cryptography"],"prefix":"10.4018","volume":"6","author":[{"given":"Ram Chandra","family":"Barik","sequence":"first","affiliation":[{"name":"National Institute of Technology, Durgapur, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suvamoy","family":"Changder","sequence":"additional","affiliation":[{"name":"National Institute of Technology, Durgapur, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sitanshu Sekhar","family":"Sahu","sequence":"additional","affiliation":[{"name":"Birla Institute of Technology, Mesra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"IJRSDA.2019010102-0","doi-asserted-by":"publisher","DOI":"10.1006\/inco.1996.0076"},{"key":"IJRSDA.2019010102-1","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2012.2190082"},{"key":"IJRSDA.2019010102-2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2007.05.011"},{"key":"IJRSDA.2019010102-3","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2006.884916"},{"key":"IJRSDA.2019010102-4","first-page":"2172","article-title":"Image size invariant visual crypto-graphy","volume":"10","author":"R.Ito","year":"1999","journal-title":"IEICE Transaction Fundamental Electronic Communication Computing"},{"issue":"3","key":"IJRSDA.2019010102-5","doi-asserted-by":"crossref","first-page":"243","DOI":"10.1016\/j.jvlc.2013.11.001","article-title":"A new visual cryptography with multi-level encoding.","volume":"25","author":"C.
