One of the questions business owners ask most before adopting electronic signing is: is it secure? And could someone forge my signature? The short answer is that the security of an electronic signature has little to do with how the signature looks on screen, and everything to do with the evidence surrounding it: who signed, how the platform verified their identity, when they signed, and whether the document changed after signing. A drawn signature on its own is an image that can be copied, whereas a signature surrounded by complete evidence is hard to deny and easy to catch tampering with.
By contrast, the paper signature that many consider safer has been forged for centuries, and detecting the forgery usually requires a handwriting expert and lengthy procedures. In this guide we explain the real sources of risk in electronic signing, the layers of protection you should look for, and how to protect your contracts from fraud in practice.
First: What does "forging" an electronic signature mean?
Why it matters: Understanding the shape of the risk is the first step in facing it. In the digital environment, forgery rarely means imitating the look of a signature. It takes other forms: someone signing while impersonating another, a document being altered after it is signed, or the signer later claiming they never signed at all. Each of these has a different means of protection.
How to do it properly: Think of the three questions that will be asked in any dispute: is the signer really the intended person? Is the document in front of us the same one that was signed? And when did the signing take place? A secure platform keeps a documented answer to each of these questions.
| Form of risk | Question it raises | Means of protection |
|---|---|---|
| Impersonating the signer | Did the intended person sign? | A verification code to their email or phone, identity confirmation with an official document, or a token |
| Altering the document after signing | Did the text change? | The document's digital fingerprint |
| Tampering with the date | When was it actually signed? | The trusted timestamp |
| Denying the signature | Can the signer disown it? | The evidence record and event log |
Common mistake: Judging a platform's security by how attractive the signature looks or how easy it is to draw. That says nothing about the strength of evidence.
Example: An employee sent a contract as an ordinary file by email, and the other party printed it, signed it, photographed it, and sent it back. In the dispute the other party claimed the second page had been swapped, and the company had nothing to prove otherwise.
Second: Verifying the signer's identity
Why it matters: The weakest link in any signature is knowing who signed. If the signing link reaches another person, or someone uses another's email, a contract can be signed in the name of someone who did not sign it. This is why verification methods are graded by the importance and value of the contract.
How to do it properly: Choose the verification level suited to each type of contract. For simple everyday contracts, a one-time verification code sent to the signer's email or to their phone via WhatsApp is usually enough. For higher-value contracts, identity confirmation with an official document and a face image through a specialist external provider is preferable. The strongest route in Egypt is signing with a token issued by a certification provider licensed by the Information Technology Industry Development Agency (ITIDA).
| Verification level | When it suits |
|---|---|
| Verification code by email or WhatsApp | Recurring low-risk contracts |
| Identity confirmation with an official document | Financial contracts, leases, and contracts with new parties |
| Token signature | High-value contracts or those likely to be disputed |
Common mistake: Using the same level for every contract. Excessive verification on simple contracts irritates signers, and weak verification on large contracts leaves a gap.
Example: A finance company used to rely on sending the link to an email address, and an attempted signing appeared from someone using an email carrying a real customer's name. When it added identity confirmation with an official document for financing contracts, impersonation became far harder.
Third: The digital fingerprint and detecting alteration
Why it matters: Even if the signer is the right person, the question remains: is the text in front of us today the same one they signed? On paper a page can be swapped, and in digital files a number or clause can be altered. The digital fingerprint is the tool that answers this question precisely.
How to do it properly: A digital fingerprint is a value computed from the document's content by a fixed algorithm, and any change, even to a single character, produces a completely different fingerprint. If the document's fingerprint is stored at the moment of signing, it can later be recomputed and compared. If they match, the document has not changed; if they differ, it has been altered.
The great advantage of the fingerprint is that it needs no expert and no personal opinion: the comparison is either a match or a difference, and any party can run it themselves through the verification page.
Common mistake: Relying on the file name or its modified date on the computer. Such data changes easily and proves nothing about the content.
Example: A tenant produced a copy of a lease with a monthly rent lower than the agreed amount. When the fingerprint of his copy was compared with the one recorded at signing, the difference showed immediately, and it was established that the copy had been altered.
Fourth: The trusted timestamp
Why it matters: The time of signing can be decisive: was the contract signed before the offer expired or after? Before the employment relationship ended or after? A date the parties write by hand, or that their devices record, can be tampered with.
How to do it properly: A trusted timestamp is issued by an independent authority attesting that the fingerprint of a given document existed at a specific time. Proof of time therefore does not depend on the signer's device clock or on the platform's clock alone. On Wthaiq, a trusted timestamp is added to signed contracts and appears in the evidence record.
Common mistake: Confusing the date written inside the contract with the actual time of signing. The first is agreed by the parties; the second is a fact that needs independent proof.
Example: A supplier claimed he had signed the price-amendment addendum before the deadline the customer had set. The timestamp showed the signing took place two days after the deadline, and the dispute was resolved without a long fight.
Fifth: The evidence record and event log
Why it matters: In a dispute it is not enough to say "the customer signed." You need a connected chain of facts: when the link was sent, when it was opened, when the verification code was entered, from which network address, and when signing was completed. This chain is what makes denying a signature difficult.
How to do it properly: Make sure the platform keeps a record of each event in the signing cycle and gathers it in an evidence record that can be downloaded and kept. Take care to download the final copy together with its record for every important contract, and store them together in your archive.
- The time the invitation was sent and the channel it was sent through.
- The time the link was opened and the number of views.
- The verification method used and the time it succeeded.
- The signing time and network address.
- The document fingerprint and the timestamp.
Common mistake: Keeping only the signed PDF without the evidence record. The copy shows what the signature looks like; the record proves how it happened.
Example: A customer denied signing an annual service contract and said someone had used his name. The company produced the evidence record showing that the signing link was sent to his registered phone number, that the verification code was entered two minutes after it arrived, and that signing was completed minutes later, together with the document fingerprint and timestamp. Faced with this connected chain of facts, the denial became hard to sustain, and the dispute ended in a settlement instead of litigation.
Sixth: Protecting contracts from fraud in practice
Why it matters: The strongest platform will not protect you if a contract is sent to the wrong number or an incorrect email, or if an employee rushes to send a contract without review. A large part of security depends on the company's own procedures.
How to do it properly: Set clear internal rules for sending contracts, and use the platform tools that support them.
- Verify the other party's email and phone number from an independent source before sending.
- Choose the verification level suited to the contract's value.
- Use the signing order when one party must sign after another.
- Have large contracts go through a manager's approval before they are sent.
- Do not share one party's signing link with another party.
- Warn your customers that the company never asks for passwords or codes over the phone.
Common mistake: Believing technology alone is enough. A fraudulent message asking the signer to resend their verification code can open the door to impersonation however strong the platform is.
Example: A customer received a call from someone claiming to be from the company who asked for his verification code "to complete the signing." Because the company had already warned its customers not to share the code with anyone, the customer refused and reported it to the company.
Seventh: The legal framework for security in Egypt
Why it matters: Technical security is completed by legal recognition. Law No. 15 of 2004 regulating electronic signatures recognizes the electronic signature in civil, commercial, and administrative transactions, and its Executive Regulations, issued by Decree No. 109 of 2005, set the technical controls for its evidentiary weight.
How to do it properly: Understand that the strength of evidence is graded. A signature with a token issued by a certification provider licensed by ITIDA enjoys the highest degree of evidentiary weight under the law. Other methods, such as signing with a verification code or after identity confirmation, draw their strength from the evidence surrounding them, and the judge assesses them according to the proof presented.
Common mistake: Assuming every signing platform is a certification authority. Certification authorities are specific licensed entities; platforms accept signatures made with the tokens they issue, or offer other methods supported by evidence.
Example: A contracting company that handles high-value contracts decided to sign its main contracts with a token, and to rely on a verification code and identity confirmation for small purchase orders. With this split it combined the highest evidentiary weight where it is most needed with ease of signing in everyday transactions.
Eighth: The security of your own account on the platform
Why it matters: Many people focus on the signer's security and forget that the company's account on the platform is the door through which contracts are sent. If someone gets into your account, they can send contracts in your company's name, or see your contracts and your customers' data. Protecting the account is therefore an integral part of signing security.
How to do it properly: Turn on two-step verification through an authenticator app, and keep the backup codes in a safe place. Give each team member their own account with permissions that suit their role instead of everyone sharing one account. Periodically review the list of devices connected to your account, and end any session you do not recognize. These simple steps prevent most cases of unauthorized access.
Common mistake: Sharing a single login among several employees. This makes it impossible to know who sent a particular contract, and makes revoking the access of an employee who has left the company complicated, because changing the login disables everyone.
Example: A small company used one account for its entire sales team. When one employee left, he kept access for weeks without anyone noticing. After the company created an account for each member and turned on two-step verification, suspending any member took a moment, and the log showed who sent each contract.
Review checklist for signing security
- Is the identity verification method suited to the contract's value?
- Does the platform store a digital fingerprint of the document at the moment of signing?
- Is a trusted timestamp added to the contract?
- Is a downloadable evidence record available?
- Is there a verification page any party can consult?
- Have you verified the other party's contact details before sending?
- Do large contracts have internal approval before sending?
- Do you keep the final copy and its record in your archive?
Frequently asked questions
Is an electronic signature more secure than a paper signature?
When it is backed by identity verification, a digital fingerprint, a timestamp, and an evidence record, tampering with it is easier to detect than forgery of a paper signature, which usually requires a handwriting expert. A drawn signature alone without evidence does not offer this level.
Can my drawn signature be copied and placed on another contract?
The signature image can be copied, but the other contract would not carry an evidence record proving you signed it, and its fingerprint would not match any signing record in your name. This is why the value of an electronic signature lies in the evidence, not the image.
What should I do if I receive a signing link from an unknown source?
Do not enter any code or open the link before confirming the sender by an independent means, such as calling them on a number you know. If you doubt the message, report it to the organization it supposedly came from.
Can a signed contract be verified without an account on the platform?
That depends on the platform. On platforms that offer a public verification page, entering the verification number printed on the contract is enough to see its status, its parties, and its signing time.
What is the strongest signing method in terms of evidentiary weight in Egypt?
Signing with a token issued by a certification provider licensed by ITIDA, because it is tied to a digital certificate issued to a specific person after verification of their identity.
The security of an electronic signature is measured not by appearance but by the evidence around it and the procedures your company follows. Choose the right verification level, keep the evidence record, and warn your customers about fraud tactics. If you want to send your contracts with complete evidence for every step, you can create your Wthaiq account.
