Frequently Asked Questions

What is the difference between a regular screenshot and a TrueScreen notarization?
A regular screenshot is just an image file with no proof of when, where or how it was taken: it can be easily edited or fabricated. A TrueScreen notarization captures the screenshot together with a complete web archive (MHTML), DOM integrity hashes, page metadata, security state and performance data. Everything is packaged into a tamper-proof archive with a digital signature and qualified timestamp, creating a forensic artifact with full legal value.
Is the notarization legally admissible in court?
Yes. Every notarization includes a digital signature and qualified timestamp compliant with the eIDAS regulation, and follows the ISO/IEC 27037 standard for digital evidence handling. The forensic report documents the complete chain of custody from capture to certification, making it admissible as evidence in legal proceedings across EU jurisdictions.
Which browsers are supported?
The extension is available for Google Chrome and is compatible with all Chromium-based browsers that support Chrome extensions, including Microsoft Edge and Brave.

Domande Frequenti

Qual è la differenza tra uno screenshot normale e una certificazione TrueScreen?
Uno screenshot normale è semplicemente un file immagine senza alcuna prova di quando, dove o come sia stato acquisito: può essere facilmente modificato o falsificato. Una certificazione TrueScreen cattura lo screenshot insieme a un archivio web completo (MHTML), hash di integrità del DOM, metadati della pagina, stato di sicurezza e dati sulle prestazioni. Il tutto viene confezionato in un archivio a prova di manomissione con sigillo digitale e marca temporale qualificata, creando un artefatto forense con pieno valore legale.
La certificazione è ammissibile in tribunale?
Sì. Ogni certificazione include un sigillo digitale e una marca temporale qualificata conforme al regolamento eIDAS e segue lo standard ISO/IEC 27037 per la gestione delle prove digitali. Il report forense documenta la catena di custodia completa dall'acquisizione alla certificazione, rendendola ammissibile come prova nei procedimenti legali in tutte le giurisdizioni UE.
Quali browser sono supportati?
L'estensione è disponibile per Google Chrome ed è compatibile con tutti i browser basati su Chromium che supportano le estensioni Chrome, inclusi Microsoft Edge e Brave.
Posso certificare pagine che richiedono il login?
Sì. L'estensione cattura esattamente ciò che è visibile nel viewport del browser. Se sei autenticato su un sito web e puoi vedere il contenuto, l'estensione può certificarlo. Le tue credenziali di accesso non vengono mai consultate o memorizzate da TrueScreen.
L'estensione è gratuita?
L'estensione è gratuita da installare e utilizzare. Ogni certificazione consuma un credito dal tuo account TrueScreen. I crediti possono essere acquistati dal Web Portal TrueScreen. È necessario un account TrueScreen: puoi registrarti gratuitamente.
Ho bisogno di un account TrueScreen?
Sì. Puoi accedere con le tue credenziali TrueScreen esistenti (email, Google, Microsoft) o tramite il SSO della tua azienda. Se non hai un account, puoi registrarti gratuitamente dal Web Portal TrueScreen.
Qual è la differenza tra la Chrome Extension e il Forensic Browser?
La Chrome Extension è progettata per la certificazione delle pagine web con un click direttamente dal browser esistente: veloce, leggera, zero configurazione. Il Forensic Browser è un'applicazione desktop dedicata per scenari forensi avanzati: sessioni di navigazione con cattura multi-screenshot, registrazione video, certificazione di meeting online e certificazione email. Inizia con l'estensione per le prove web quotidiane, passa al Forensic Browser quando hai bisogno di funzionalità a livello di sessione.
Dove vengono conservati i miei dati?
Tutti i dati delle certificazioni sono conservati esclusivamente in data center dell'Unione Europea. TrueScreen è pienamente conforme al GDPR. Le tue certificazioni sono accessibili dal Web Portal TrueScreen e possono essere condivise o scaricate in qualsiasi momento.
