Establish Non-Repudiation of your contracts for Life

Expand your Digital Trust with Time Stamping

Time Stamping helps to establish the time of signature in a tamper-proof manner to enable Long Term Validity of signed data
Validate Transactions with emTSA

Validate Transactions with emTSA

Ensure the existence and validity of any given document or transaction through the provision of a precise timestamp, affirming the exact date and time of the transaction's occurrence

Long Term Validity (LTV)

Long Term Validity (LTV)

Enable LTV Signing in your ecosystem to store digitally signed data for long duration while maintaining the validity of signature (at the time of signing), even beyond the expiry of the actual certificate used to sign.

Ensure Regulatory Compliance

Ensure Regulatory Compliance

Time stamping and LTV enablement can help regulated organizations effectively comply with retention requirements of signed contracts in a cost effective and digitally verifiable manner.

Enhanced Transaction Security

Enhanced Transaction Security

Time stamping helps to maintain the integrity of the time a particular data or document was signed. Effectively, this helps prevent any attempts at modifying the time of a signed activity, which often can have legal and commercial consequences.

Legal Non-Repudiation

Legal Non-Repudiation

emTSA ensures undeniable proof of a transaction's or contract's time of execution. It can even adhere to the country's primary source of time as per regulatory requirements to ensure that the time captured is not the system time, but a central source of time for the country. This can ensure legal non repudiation of the contract or data at any point in time in the future.

Establish the time through multiple methods

Source Time from a certified provider

emTSA can plug into any National Provider for the Official Time in a specific country to ensure that the time captured and used in signed data is in-line with the country's regulations and requirements. A great way to run time-stamping for regulated use cases in countries where such providers exist.

Source time from NTP Devices

Source time from NTP Devices

emTSA can integrate with NTP devices to establish the precise time in a particular location often given as an output from NTP devices. This time can then be used to timestamp data or documents as a precise and uniform approach and avoids client interpretation of time.

Source time from the System

Source time from the System

For less sensitive use cases, emTSA can pull the time from the signer's system, which is then used to time stamp documents. In such cases, emTSA can be configured to present the time in addition to the time zone to establish GMT based time for any signed data or document.

Frequently Asked Questions

eMudhra's emTSA is a trusted third-party service that provides a precise and accurate timestamp for digital transactions. It validates the exact time a transaction has occurred, ensuring data authenticity, non-repudiation, and integrity.

eMudhra's emTSA utilizes advanced cryptographic techniques to securely timestamp a digital transaction. This timestamp is tied to the transaction data, offering a reliable and verifiable record of the time the transaction took place.

Capturing the time (digitally) when a contract or data was signed allows systems to establish and maintain the status of the certificate used to sign the document (or data) at the time of signing. This helps to present the then-prevailing status of the certificate at a future date, even if the actual certificate itself as expired.

eMudhra's emTSA ensures document integrity by verifying the time of the transaction. Any changes to the document after the timestamp have been applied can be easily detected, which helps prevent data tampering and enhances the document's overall integrity.

eMudhra's emTSA enhances security by providing a timestamp that adds to the authenticity of the transaction. This makes it difficult for unauthorized entities to tamper with the transaction, ensuring the security of the digital interactions.

While the digital signature certificate establishes the identity of the user and integrity of the signed data, time-stamping enhances non repudiation by establishing the time the data was signed.

eMudhra's emTSA helps meet regulatory compliance by providing auditable trails of digital activity. The timestamps can serve as proof of compliance during audits, demonstrating that transactions have taken place at specific times.

Yes, eMudhra's emTSA adheres to international standards, making it a globally accepted service for verifying the time of digital transactions.

By verifying the time and integrity of digital transactions, eMudhra's emTSA boosts confidence among clients, stakeholders, and partners. This promotes trust in digital interactions, contributing to a company's reputation.

emTSA is flexible enough to accomodate to multiple sources of time. There are generally a few ways this can happen. emTSA can source the time from the trusted time provider for a given country. Alternately, emTSA can also plug into NTP devices that are often used to establish precise time in a location. For less sensitive use cases, emTSA can also be configured to use the system time.
