What is the digital signature ?
 

Hi



Please tell me What is the digital signature ?

A mathematical scheme for demonstrating the authenticity of a digital message or document..

yes, you are right

Thanks for reply.

Digital signature is basically an online signature used for building authority to the website specifically used for transcations and authenticity building..

I am sure online signature is digital signature.

A digital signature(standard electronic signature) takes the idea of customary paper-based marking and transforms it into an electronic "finger impression." This "unique mark," or coded message, is novel to both the archive and the underwriter and ties them together. Advanced marks guarantee the genuineness of the underwriter. Any progressions made to the report after it has been marked negate the mark, consequently securing against mark imitation and data altering. Thusly, Digital signature help associations support endorser genuineness, responsibility, information honesty and the non-denial of marked electronic archives and structures. Watch a feature to perceive how a digital signature works.

Yeah, I agree that digital signature is online signature.

Digital signature is a mathematical technique used to validate the authenticity and integrity of a message, software or digital document.

Digital signature is the signature which should be shown on the digital screen and with the help of digital signature you can promote your website. This type of signature would be mostly shown in the forum sites.

yes, you are right

A digital signature is a mathematical scheme for demonstrating the authenticity of a digital message or documents. A valid digital signature gives a recipient reason to believe that the message was created by a known sender, that the sender cannot deny having sent the message, and that the message was not altered in transit.

A digital signature is basically a way to ensure that an electronic document is authentic.

Yeah, that truely explains it all. Digital signature is an online signature which shows authority of a website.

The digital signature is a mathematical technique used to validate authenticity and integrity of the message it will be used fro cryptographic photo suites,financial transaction,contract management.

A digital code (generated and authenticated by public key encryption) which is attached to an electronically transmitted document to verify its contents and the sender's identity.

i think thats the some kind of a website link for people

Bob
(Bob's public key)

(Bob's private key)

Bob has been given two keys. One of Bob's keys is called a Public Key, the other is called a Private Key.

Bob's Co-workers:

Anyone can get Bob's Public Key, but Bob keeps his Private Key to himself
Pat Doug Susan
Bob's Public key is available to anyone who needs it, but he keeps his Private Key to himself. Keys are used to encrypt information. Encrypting information means "scrambling it up", so that only a person with the appropriate key can make it readable again. Either one of Bob's two keys can encrypt data, and the other key can decrypt that data.

Susan (shown below) can encrypt a message using Bob's Public Key. Bob uses his Private Key to decrypt the message. Any of Bob's coworkers might have access to the message Susan encrypted, but without Bob's Private Key, the data is worthless.

With his private key and the right software, Bob can put digital signatures on documents and other data. A digital signature is a "stamp" Bob places on the data which is unique to Bob, and is very difficult to forge. In addition, the signature assures that any changes made to the data that has been signed can not go undetected.


To sign a document, Bob's software will crunch down the data into just a few lines by a process called "hashing". These few lines are called a message digest. (It is not possible to change a message digest back into the original data from which it was created.)

Bob's software then encrypts the message digest with his private key. The result is the digital signature.

thank you for your information . That is usefull

The digital signature way to ensure the electronic document is authentic these type of digital signature rely on certain types of encryption ensure authentication both send and receive process work in the hand of digital signature.

Digital Signature is a type of electronic signature that encrypts documents with digital codes that are particularly difficult to duplicate.

A digital code which is attached to an electronically transmitted document to verify its contents and the sender's identity.

not simply ink on paper, online signatures can be as below

A digital signature is a mathematical scheme for demonstrating the authenticity of a digital message or documents. A valid digital signature gives a recipient reason to believe that the message was created by a known sender, that the sender cannot deny having sent the messages, and that the message was not altered in transit .

Digital signatures are a standard element of most protocol suites, and are commonly used for software distribution, financial transactions, contract management software, and in other cases where it is important to detect forgery or tampering.

A digital signature (not to be confused with a digital certificate) is a mathematical technique used to validate the authenticity and integrity of a message, software or digital document.

yes. that is
