Query: Handwritten Text Image Authentication using Back Propagation   Authentication is the act of confirming the truth of an attribute of a datum
or entity. This might involve confirming the identity of a person, tracing the
origins of an artefact, ensuring that a product is what it's packaging and
labelling claims to be, or assuring that a computer program is a trusted one.
The authentication of information can pose special problems (especially
man-in-the-middle attacks), and is often wrapped up with authenticating
identity. Literary can involve imitating the style of a famous author. If an
original manuscript, typewritten text, or recording is available, then the
medium itself (or its packaging - anything from a box to e-mail headers) can
help prove or disprove the authenticity of the document. The use of digital
images of handwritten historical documents has become more popular in recent
years. Volunteers around the world now read thousands of these images as part
of their indexing process. Handwritten text images of old documents are
sometimes difficult to read or noisy due to the preservation of the document
and quality of the image [1]. Handwritten text offers challenges that are
rarely encountered in machine-printed text. In addition, most problems faced in
reading machine- printed text (e.g., character recognition, word segmentation,
letter segmentation, etc.) are more severe, in handwritten text. In this paper
we Here in this paper we proposed a method for authenticating hand written text
images using back propagation algorithm..
