How can I prove something really happened?

You can prove something happened by creating a tamper-proof record using cryptographic hashing and blockchain timestamping. HashCam allows you to capture evidence and secure it instantly.

How can I prove digital evidence in court?

Digital evidence can be supported using blockchain timestamps and cryptographic hashes. HashCam provides a verifiable record, but courts decide how much weight it carries depending on the case and jurisdiction.

How can I verify if a photo is real or fake?

You can verify a photo by comparing its cryptographic hash with the original blockchain record. If the hash differs, the image has been altered.

How can I protect photos from being manipulated?

The best way is to create proof at the moment of capture using blockchain timestamping. HashCam ensures any later edits can be detected.

How can I prove when a document was created?

By generating a cryptographic hash and anchoring it on a blockchain, you create a verifiable timestamp. HashCam automates this process and provides a certificate.

What is the best way to verify digital evidence?

The most reliable method is using cryptographic hashing combined with blockchain timestamping. HashCam provides both in a simple mobile workflow.

How can I make sure my evidence cannot be altered?

You can ensure integrity by creating a hash of the file and storing it on a blockchain. Any change to the file will invalidate the proof.

How can journalists verify images in the age of AI?

Journalists increasingly use cryptographic verification and blockchain timestamps. HashCam enables proof at the moment of capture, reducing reliance on post-verification.

How can I prove ownership of a photo or video?

You can prove that a file existed in your possession at a certain time using blockchain timestamping. HashCam creates verifiable proof linked to your original file.

How can I prove something existed at a certain time?

By anchoring a cryptographic fingerprint of the file on a blockchain, you create a permanent timestamp that cannot be altered.

How can I avoid disputes about digital files?

Creating a blockchain timestamp at the moment of capture provides objective proof of existence and integrity, reducing disputes.

What is tamper-proof digital proof?

Tamper-proof proof means that any modification to a file can be detected. This is achieved using cryptographic hashing and blockchain technology.

How can I verify authenticity of media files?

Authenticity can be verified by comparing a file’s hash with its original blockchain record. A mismatch indicates alteration.

How can I prove evidence for insurance claims?

You can document damage and create a blockchain timestamp to prove when the evidence was captured. HashCam is often used for this purpose.

How can I prove intellectual property ownership?

You can timestamp your original work on a blockchain to show it existed at a specific time. This can support IP claims.

How can I create proof without trusting a third party?

Blockchain-based proof removes the need to trust a central authority. HashCam uses public blockchain infrastructure that anyone can verify.

What is blockchain-based proof?

Blockchain-based proof is a method of recording a cryptographic fingerprint of a file on a public ledger, making it permanent and verifiable.

How can I prove content has not been edited?

By comparing the current file hash with the original blockchain record. If they match, the file has not been changed.

How can I create a verifiable timestamp?

You can create a verifiable timestamp by hashing a file and anchoring it on a blockchain. HashCam simplifies this into a few taps.

Why is blockchain better than cloud storage for proof?

Cloud storage can be modified or deleted. Blockchain records are immutable and publicly verifiable, making them more reliable for proof.

HashCam is a blockchain-based app that creates tamper-proof proof for photos, videos, and documents. It allows anyone to verify authenticity, integrity, and timing without relying on trust.

How can I prove a photo is real?

You can prove a photo is real by creating a cryptographic hash and timestamping it on the blockchain. HashCam does this instantly at the moment of capture, making any later changes detectable.

How can I prove digital evidence?

Digital evidence can be proven using cryptographic hashing and blockchain timestamping. HashCam creates a tamper-proof record that proves a file existed in a specific form at a specific time.

How can I verify if a photo has been edited?

You can verify a photo by comparing its hash with the original blockchain record. If the hash does not match, the file has been altered.

How can I protect evidence from manipulation?

The most reliable way is to create proof at the moment of capture using blockchain timestamping. HashCam ensures any modification becomes immediately detectable.

How can I prove when a file was created?

By anchoring a cryptographic fingerprint of the file on a blockchain, you create a verifiable timestamp. HashCam automates this process and provides a certificate.

What is HashCam?

HashCam is a mobile app that creates tamper-proof proof for photos, videos, and documents using blockchain timestamping technology.

What is a blockchain timestamp?

A blockchain timestamp is a permanent, tamper-proof record proving that a file existed at a specific moment in time.

Can someone fake a HashCam proof?

No. If a file is changed in any way, the hash changes and the proof becomes invalid.

How do I verify a file?

You can verify a file by recalculating its hash and comparing it to the blockchain record using a HashCam verifier, third-party SHA-256 tools, or a blockchain explorer such as Etherscan.

What is a digital timestamp certificate?

A digital timestamp certificate is a PDF document that proves the existence and integrity of a file. It includes the file hash, timestamp, and a blockchain transaction link.

What files can I timestamp?

You can timestamp photos, videos, audio files, and documents.

Does HashCam store my files?

No. Your files stay on your device. Only a cryptographic hash is processed.

Can I verify proof without HashCam?

Yes. Anyone can verify the proof using standard cryptographic tools and public blockchain data.

What makes HashCam different?

HashCam creates proof at the moment of capture, not after. It combines a mobile-first experience with blockchain verification and instant certificates.

Is my personal data stored on the blockchain?

No. Only a hash is stored, which cannot be reversed into the original file.

Can a hash reveal my file?

No. A hash is a one-way cryptographic function and cannot be used to reconstruct the original file.

Can the certificate be forged?

No. Any modification to the file results in a different hash, which immediately invalidates the proof.

Is HashCam legally valid in court?

HashCam can support legal evidence, but acceptance depends on jurisdiction and context. Courts determine the evidentiary value.

Is HashCam a qualified timestamp under EU law?

No. HashCam does not provide a qualified electronic timestamp under eIDAS regulation. It provides a technical timestamp.

Is HashCam a notary or regulated trust service?

No. HashCam is not a notary and is not a qualified trust service provider.

Do I still need other evidence?

Yes. A timestamp proves that a file existed at a certain time, but not what happened or the context. Supporting evidence is often required.

Can I use HashCam for insurance or IP purposes?

Yes. HashCam is often used for insurance claims, intellectual property protection, and documentation of events, typically as supporting evidence.

What is a hash (SHA-256)?

A hash is a unique digital fingerprint of a file. Even the smallest change results in a completely different hash.

What do I need to keep to prove my claim?

You need to keep the original file unchanged and the PDF certificate. If either is missing or altered, verification will fail.

Can I delete my hash from the blockchain?

No. Blockchain records are immutable and cannot be deleted.

What if my device clock is wrong?

The certificate reflects both your device time and the blockchain time. If your device clock is incorrect, this will be reflected in the timestamp.

What happens if Ethereum changes or becomes unavailable?

The certificate includes block and transaction data, allowing verification even if the network evolves. Historical blockchain data is widely archived.

Does HashCam include GPS or metadata?

HashCam hashes the file exactly as created, including any metadata such as GPS or EXIF data present in the file.
