What is an electronic seal?
An electronic seal, often called an “eSeal” is a digital equivalent of a traditional physical seal or stamp used to authenticate and secure electronic documents or data. Electronic seals are primarily used in digital or electronic transactions to ensure the integrity and authenticity of the documents, much like how physical seals or signatures are used in the paper-based world.
A digital seal is a specific type of electronic seal that is used to authenticate and secure electronic documents or data through the application of cryptographic techniques. It involves using digital signatures to ensure the authenticity and integrity of digital content.
While both electronic seals and digital seals are used for document authentication, the key distinction lies in the level of security and formality they offer. Electronic seals are more versatile but less secure, whereas digital seals provide a high level of security and are typically used for formal, legally binding documents and transactions.
Evolution from traditional seals
Since the beginning of recorded history till date, we have had a wide range of seal practices. Among these, wax and rubber seals have been a popular choice.
It was governments and royalties who started employing distinct designs to ensure the security of their transactions and maintain confidentiality.
However, these historically significant traditional seals come with several drawbacks. The wax seals are susceptible to cracking and chipping. Environmental factors like temperature and humidity would distort the seal impression, making them less durable and practical. This affects the security of the document.Â
In response to these challenges and in light of digital advancements, digital evolution gave a new face to sealing practices. Now the documents are sealed online.
How electronic seals work
Electronic seals apply digital or electronic marks to documents or data to confirm their authenticity and integrity. The exact process can vary depending on the technology and methods used, but here’s a general overview of how electronic seals typically work:
- Document preparation: The process begins with the creation or preparation of the electronic document that needs to be sealed. This document can be in various formats, such as PDF, Word, or other electronic data.
- Seal application: The entity or individual responsible for sealing the document uses specific software or tools designed for electronic sealing. The seal can take different forms, such as a visual image, a digital signature, or a watermark, depending on the chosen method.
- Authentication: If the electronic seal involves cryptographic methods, a private key is used to create a unique digital signature for the document. This signature is generated based on the document’s content and other parameters, and it confirms the authenticity of the document.
- Timestamp: In some cases, a timestamp is applied to record the date and time of the sealing. This helps establish when the document was sealed and can prevent backdating.
- Distribution: The sealed document is then distributed to the intended recipients, who may need to verify the seal’s authenticity.
- Verification: Recipients use the corresponding public key or other verification methods to check the document’s seal. If the seal is valid, it indicates that the document has not been tampered with and that it comes from a legitimate source.
- Record Keeping: Many organizations maintain records of sealed documents and their associated seals for auditing and legal purposes.

Components of an electronic seal
Electronic seals consist of several key components that work together to create a secure and verifiable digital seal for electronic documents or data. These components typically include:
1. Digital signatureÂ
This is a cryptographic technique that creates a unique and tamper-evident signature for the document. It is generated using a private key and can be verified using a corresponding public key. The digital signature ensures the authenticity and integrity of the document.
2. Private key
The private key is a secret cryptographic key held by the entity or individual applying the electronic seal. It is used to create the digital signature and should be securely stored and protected to prevent unauthorized access.
3. Public key
The public key is made available to those who need to verify the electronic seal. It is used to confirm the authenticity of the digital signature. Unlike the private key, the public key is not kept secret and can be freely distributed.
4. Certificate authority (CA)
A certificate authority is a trusted third-party organization that issues digital certificates. These certificates bind a public key to the identity of the entity or individual holding the private key. The CA’s role is to vouch for the authenticity of the public key and the associated electronic seal.
5. Hashing algorithm
A hashing algorithm creates a fixed-size, unique representation (hash) of the document’s content. This hash is included in the digital signature and is used to verify the document’s integrity. Any change to the document will result in a different hash.
6. Seal image or symbol
In some cases, an electronic seal may include a visual representation of the seal, such as a digital image or symbol, which can be added to the document to indicate its authenticity and to replicate the traditional concept of a physical seal.
7. Timestamp
A timestamp is often included to record the date and time when the electronic seal was applied to the document. This provides additional evidence of when the document was sealed and helps prevent backdating.
8. Authentication and verification software
To apply electronic seals and verify their authenticity, specialized software is used. This software typically handles the cryptographic operations, key management, and digital signature generation and verification.
Legal validity and compliance of electronic seal
Electronic seal regulations and their recognition in court are subject to the laws and regulations of the specific region or country. Here’s a general overview:
eSignature regulations
US ESIGN Act and the European eIDAS Regulation, generally provide a legal framework for using electronic signatures and seals. However, the recognition and acceptance of electronic seals can depend on several factors, including the level of security and authentication they offer. If electronic seals meet the regulatory requirements for electronic signatures and are considered secure and tamper-evident, they are more likely to be legally valid and compliant.
Admissibility in court
The admissibility of electronic seals in court depends on the legal system of the jurisdiction and the specific rules regarding evidence and document authenticity. In many countries, electronic seals can be admitted as evidence in court proceedings if they meet certain criteria:
- Compliance with eSignature regulations: Seals that comply with relevant eSignature regulations and standards are more likely to be accepted in court.
- Security and integrity: The court will want assurance that the electronic seal provides a high level of security and ensures the integrity of the document. This may involve the use of digital signatures and strong authentication methods.
- Chain of custody: Maintaining a clear and documented chain of custody for the electronically sealed document can also enhance its admissibility in court.
- Expert testimony: In some cases, expert testimony or the testimony of a qualified witness may be required to explain the authenticity and security of the electronic seal.
