By Gerard Volegna


Because of the new technology as innovation that is happening in the world, many tasks are being simplified by new invention which is so helpful for lots of people today. Business is just one of the things that have been helped by new technology today. Because of new technology like email, online shops and web sites, paper based transactions are minimized or even remove this kind of transaction as new kind of transaction is faster and more effective. As the paper transaction is remove, the loss of documents are also minimize because all transactions and data are now in the computer where it is stored. It is always important for clients and customers and as well as the company to take good care of files and documents that is why the best thing that is possible to do would be done.

The digital signature is an application in devices like iPhone, android devices and other devices which generates a digital copy of signature that is possible when the user puts his or her signature in a touch screen device with the digital signature application. After using the stylus to put the signature in the screen, the application would then recognize what was written in the screen and then create a digital copy of it.

After it generates a digital copy of a signature it could then be passed through the computer which is the main tool today for business and other transactions in company. When the digital signature is in the computer, it could then be put to files and documents that need the signature. Also, this signature could be passed through other people that need it through the use of email. With new technology and great innovation towards advancement, there are lots of things today that really giving convenience to people.

The digital signature is used for the user to create a digital copy of a signature which would be placed in files and documents in the computer where it would then be passed to other people mainly the clients and customers of the company or other companies and other authorized person that are needing the document or the signature only. Because it is easy to be transported, the signature could be used to other kinds of documents and also cannot be imitated by others.

To be able to make this work, you have to use special software to obtain a message hash. Then you will use your private key which has given to you by the public-private key authority for you to be able to encrypt the hash. Take note that message encryption is optional, you can send unencrypted message with a digital signature if it doesn't matter to you who see the message and you're only after the assurance of the receiver that it is from you. The encrypted hash that you have now is then your digital message. The receiver then makes a hash of the message to ensure that it is from you and it is intact. After that, public key is used now to decrypt the hash message and if the hashes matched it is then valid.
