A digital signature is a digital code (generated and authenticated by public-key encryption) that is attached to an electronically transmitted document to verify its contents and the sender’s identity.

If assurance is required that a message or an accompanying document has not been altered during transmission, a digital signature will prevent unknown alterations from going unnoticed. If the digitally signed content is altered, the signature will be invalidated, thus alerting the sender and receiver of a breach. The applied cryptographic functions will prevent a new and valid signature from being produced for that message.

It has a multi-layered secured signing process to maintain document integrity. It replaces the manual signing process and paperwork to sign and notarize the legal and other documents, thus reducing the cost and time. With the third-party tools integrated, the user can observe/witness the entire signing process online without being physically present for being a witness. It is a multi-tenant application that enables the client admin of the tenant to manage users, user privileges, manage roles, view logs and configure advanced settings.

Yes, Cygnature is safe to use for signing any document using any sort of digital signature, including electronic, digital, and biometric.

In the backend, we use Blockchain, which ensures utmost security by encrypting your file and signature and generating a unique hash code. The use of Blockchain technology makes the document tamper-proof, preventing any alterations to the document or the signing process.

  • Integrity – Ensuring that the copy of a document has the same content as the original.
  • Authentication – verify the authenticity of documents and ensure they are signed by the person who claims to have created or changed them.
  • Non-repudiation – Not allowing someone to deny the authenticity of their signature on a document or sending the message in the first place, as long as each iteration is stored in the Blockchain.

A Blockchain certificate records the signing process by keeping track of the Signers following certain parameters like:

  • IP Address of signers
  • Time and Date of Singing’
  • Geo Location
  • Latitude Longitude
  • Device
  • Browser

There are typically three algorithms involved with the digital signature process:

  • Key generation – This algorithm provides a private key and its corresponding public key.
  • Signing – This algorithm produces a signature upon receiving a private key and the message that is being signed.
  • Verification – This algorithm checks for the authenticity of the message by verifying it along with the signature and public key.

In private tenant architectures, a customer will have a singular instance of an application dedicated to them.

The Information Technology Act, 2000 (IT Act) confirms that contracts enforceability cannot be denied merely because they are signed electronically. On the contrary to popular belief, e-Signatures have been legally valid in India for over 18 years now. The Information Technology Act (IT Act), passed in 2000, granted e-Signatures the same legal status as handwritten signatures.

The IT Act recognizes the following two types of signatures:

(1) e-Signatures that combine an Aadhaar with an e-KYC service

Users with an Aadhaar ID and Unique Identification Number (UAN) issued by the Indian government to all Indian residents can use an online e-Signature service to sign documents online securely. In this case, the online e-Signature service integrates with an Application Service Provider (ASP) to provide users with a mobile or web app interface that they can interact with.

(2) Digital signatures that are generated by an asymmetric crypto-system and hash function

An ‘asymmetric crypto system’ refers to a secure pair of keys: private and public keys. Both are unique to each user and can be leveraged to verify and create an e-Signature.

Here are the five criteria that e-Signatures need to satisfy to be valid as per the IT Act:

(1) e-Signatures must be uniquely linked to the person signing the document. This condition is met by issuing a digital certificate-based digital ID.

(2) During the signing process, the signer must have total control over the data used to generate the e-Signature. Most online e-Signature service providers allow signers to directly affix their e-Signature to the document to meet this requirement.

(3) Any alteration to the affixed e-Signature, or the document to which the signature is attached, must be detectable. This requirement is met by encrypting the document with a tamper-evident seal.

(4) There should be an audit trail of steps taken during the signing process.

(5) The digital signature certificate must be issued by a Certifying Authority (CA) recognized by the Controller of Certifying Authorities (CCA) appointed under the IT Act.

No, certain documents that require a notarial process or must be registered with a Registrar or Sub-Registrar, can only be executed using handwritten signatures to be legally enforceable. These primarily include:

(1) Negotiable instruments such as a promissory note or a bill of exchange other than a cheque

(2) Powers of attorney

(3) Trust deeds

(4) Wills and any other testamentary disposition

(5) Real estate contracts such as leases or sales agreements

Yes, it states that “All electronic signatures must meet the ESIGN, UETA and GPEA definition of electronic signature, or the basic definition of an electronic signature as required by other national and local legislation.”

Following are the parameters –

  • Intent to sign
  • Consent to do business electronically –

Electronic records may be used in transactions with consumers only when the consumer has:

  • Received UETA Consumer Consent Disclosures
  • Affirmatively agreed to use electronic records for the transaction
  • Has not withdrawn such consent
  • Association of signature with the record – To qualify as an electronic signature under the e-Sign Act and UETA, the system used to capture the transaction must keep an associated record that reflects the process by which the signature was created or generate a textual or graphic statement (which is added to the signed record) proving that it was executed with an electronic signature.
  • Record retention
  • Opt-Out Clause
  • Providing Signed Copies

  • The e-Sign Act is a federal law passed in 2000. It grants legal recognition to electronic signatures and records if all parties to a contract choose to use electronic documents and sign them electronically.
  • UETA (Uniform Electronic Transactions Act), a precursor to the e-Sign Act, was introduced in 1999 and has been adopted by 47 U.S. states and the District of Columbia, and the U.S. Virgin Islands.
  • Among other things, UETA provides that when a law requires either a writing or a signature, an electronic record or an electronic signature can satisfy that requirement when the parties to the transaction have agreed to proceed electronically.

  • UETA and the e-Sign Act solidified the legal landscape for the use of electronic records and electronic signatures in commerce by confirming that electronic records and signatures carry the same weight and have the same legal effect as traditional paper documents and wet-ink signatures.

Both laws provide the following:

  • No contract, signature, or record shall be denied on a legal basis solely because it is in electronic form.
  • A contract relating to a transaction cannot be denied legal effect solely because an electronic signature or record was used in its formation.
  • If a law requires a record in writing, an electronic one satisfies the law.
  • If a law requires a signature, an electronic signature satisfies the law.
  • Does not apply to birth, death, wedding, wills, etc., are exempted.

The state of Illinois has not adopted UETA. However, in 1999, Illinois enacted electronic signature law which favors some types of electronic signature as more trustworthy than others. Under the law, the most secure type of electronic signature is the “secure electronic signature”. Secure electronic signatures are presumed valid under the law unless there is evidence to the contrary. Under the law, it is deemed “secure” if:

  • It is created in a manner that can be considered commercially reasonable under the circumstances.
  • It is applied by all parties sin a trustworthy manner that can be verified.
  • It can be relied upon by all parties.
  • Both parties agree that the signature is “secure”.
  • It is created using an asymmetric algorithm certified by the Secretary of State.
  • It is created using a valid certificate issued by a CA in accordance with standards set by Secretary of State within the scope specified in the valid certificate and can be verified via the valid certificate public key.

The state of New York (NY) has not adopted UETA. However, since 2000, electronic signatures have been legally binding in New York under the Electronic Signatures and Records Act (ESRA). This law broadly established the legal equivalence of electronic and handwritten signatures.

  • This law broadly established the legal equivalence of electronic and handwritten signatures.
  • ESRA also created the “electronic facilitator” role within the NY Office of Information Technology Services.
  • In New York, electronic signatures have the same legal validity as handwritten signatures.

The state of Washington has not adopted UETA. However, Washington did enact the Washington Electronic Authentication Act to facilitate e-commerce, minimize fraud, and ensure the security and integrity of “e-messages”.

  • It includes wording to ensure that electronic signatures are not refused legal recognition and regulates CAs.
  • In Washington, the Secretary of State licenses and regulates CAs and oversees the rules and policies around using them.
  • In order to be considered for government use, CAs must pass specific requirements and prove that they have a trustworthy system.
  • The Secretary of State conducts periodic compliance audits of CAs and even CAs in violation.

South Africa generally follows the EU Directive on Electronic Signatures. It is considered a two-tier jurisdiction because it gives digital signatures the same status as handwritten signatures and recognizes simple electronic signatures as legal and enforceable.

  • Countries that follow this model allow companies to select different forms of signatures and customize their business processes based on the most convenient and appropriate form for each use case.
  • Consent is the prerequisite for allowing electronic signatures. However, according to Section 13(5) of the Electronic Communications and Transactions Act, if the parties have not agreed on a specific type of electronic signature as long as there is,
  • A method to identify the person and indicate the person’s approval of the communicated information.
  • The method is reliable and appropriate for the information purpose; electronic signatures are also legal, admissible, and enforceable in South Africa.

Under UAE law, a written signature is not necessarily required for a valid contract – contracts are generally valid if legally competent parties reach an agreement, whether they agree verbally, electronically or in a physical paper document. Parties sometimes must present evidence in court to prove a valid contract.

  • Leading digital transaction management solutions can provid electronic records that are admissible in evidence, under UAE laws, to support the existence, authenticity, and valid contract acceptance.

eIDAS (Electronic Identification, Authentication, and trust Services) sets out two types of electronic signature, ‘Advanced’ and ‘Qualified’.

  • ‘Advanced Electronic Signature’ is defined in Article 26.
  1. It is uniquely linked to the signatory.
  2. It is capable of identifying the signatory.
  3. It is created using electronic signature creation data that the signatory can, with a high level of confidence, use under his sole control and,
  4. It is linked to the data signed herewith in such a way that any subsequent change in the data is detectable.”
  • Cygnature offers ‘Advanced Electronic Signature’.
  • ‘Qualified’ signatures are based on ‘public-key infrastructure’ technology (PKI) and, together with a set of regulations on issuance and trust, provide a framework to add a strong level of authentication and encryption.
  • eIDAS also entrenches past commitments that underpin electronic signature, for example, the provision that an electronic signature “shall not be denied legal effect and admissibility in a legal proceeding solely on the ground that is it an electronic form or that it does not meet the requirements for qualified signature”. (Article 25.1)
  • In the UK, Qualified Certificates are primarily unused because there is no practical way to access and apply them. They are used better in EU countries where there is a national ID scheme, for example, in Spain and Estonia. Citizen IDs can become a ‘qualified certificate’ and thereby provide an avenue for Qualified Signatures to be rolled out and adopted across a whole population.
