Digital watermarking by utilizing the properties of self-organization map based on least significant bit and most significant bit

<p><span lang="EN-US">Information security is one of the most important branches concerned with maintaining confidentiality and reliability data medium for which it transmitted. Digital watermarking common techniques in this field developing greatly rapidly due to great importance represents security. Most modern systems, however, use self-organization map (SOM), safer than other algorithms because an unauthorized user cannot see result SOM's training. Our method presents a semi-fragile watermark under spatial domain using least significant bit (LSB) by relying on (MSB) when taken values equal (2 or 4 bits) depending characteristics SOM through so-called best matching unit (BMU) working determine location concealment. As result, shows us ability proposed maintain quality host retrieve data, whether binary image secret message.</span></p>
