Technological advancements have made the whole process of tax filing and submitting returns over the internet much simpler. In order to e-file income tax returns, taxpayers need to affix their digital signature onto their tax return document as a way to authenticate it. Under the IT Act 2000, a digital signature enjoys the same status as a regular signature. It attests and verifies that the taxpayer has authenticated the tax return documents in a safe environment, without fraud.
Digital signatures, which are issued by Certification Authorities, contain particulars like the taxpayer's name, public key, name of issuing Certification Authority, expiration date of public key, the digital signature and its serial number. Tampering with digitally signed documents and claiming forgery over digital signatures are not possible, considering that a number of checks are in place to substantiate the same. Documents that are digitally signed are protected from further modifications and additions post signing.
Following are some of the benefits of using digital signature:
For the purpose of knowing how a digital signature functions, one needs to first understand the elements involved in a digital signature:
Name: The primary and utmost important thing that a digital signature holds is the name of the person who would be using it or authorizing a document by its use for a variety of purposes like filing documents with relevant authorities. A digital signature also reduces chances of a fraud getting commitment under his name by another person bearing the same name.
Personal Information: Along with the full name, a digital signature also has vital and other relevant information like contact number i.e. mobile number, residential and office telephone numbers, email address, residential address, office address which may be used to locate and contact the person. This information is in an encrypted form and cannot be accessed by everybody, thus it also ensures privacy of the user.
Public Key: Every digital signature has a special public key associated with it. This key is used for encrypting and securing a document at the time it is being authorised. It plays a very important role in the verification process. There is also an expiry date for each and every digital signature, which is determined by the public key associated with it. The public key shows the time frame during which a digital signature is valid. The key also helps to reset the digital signature, if the need arises.
Serial Number: This is another key component that works as a unique identifier for a digital signature. This number is of prime importance to ensure the viability of a digital signature. The serial number is used by the certification authority who issues the digital certificate.
