Concealment of identity on the Internet requires a combination of technical tools and operational strategies. The following are some legal and compliance methods and tools for reference (for privacy protection and legal purposes only).： --- ###**1. Basic strategy** 1. **Isolate identity** -Create a **virtual identity** (such as anonymous email address, user name) that has nothing to do with the real identity, and avoid using personal information (birthday, name). - Use a disposable mobile phone number or virtual number (such as Google Voice, MySudo) to register an account. 2. **Anonymous network traffic** -**Tor browser**: Routing traffic through multi-layer encrypted nodes, hiding IP addresses (suitable for access. onion website). -**VPN (virtual private network)**: Choose a paid VPN service without logging (such as Mullvad, PROTONPN) to avoid free tools. -**Public Wi-Fi**: Temporarily use public networks that are not associated with personal devices (security needs to be paid attention to). 3. **Encrypted communication** -End-to-end encryption tools: such as Signal (instant messaging), ProtonMail (mailbox), Session (decentralized chat). - Avoid using real accounts on mainstream social platforms for sensitive exchanges. --- ###**2. Advanced tools** 1. **Operating system isolation** -**Tails OS**: A real-time system based on Linux that forces networking through Tor without leaving a trace. -**Qubes OS**: Isolate different tasks through virtual machines to prevent cross-leakage of data. -**Virtual machine**: Run an anonymous system in VirtualBox, isolated from the host. 2. **Cryptocurrency payment** -Use private currencies (such as Monero/XMR, Zcash/ZEC) for transactions to avoid Bitcoin (transaction records are public). -Blur the flow of funds through mixed currency services (such as CoinJoin). 3. **Anonymous mailbox and temporary service** -Anonymous mailboxes: ProtonMail, Tutanota, Guerrilla Mail (temporary mailboxes). -File transfer: OnionShare (based on Tor),Temp.sh (Temporary file hosting). 4. **Equipment and hardware protection** -**Physical isolation**: Use second-hand equipment or disposable mobile phones to handle sensitive tasks. -**Camera/microphone switch**: Hardware-level shutdown or physical blocking. -**Anonymous SIM card**: Purchase a prepaid card (no real name required) and activate it away from commonly used locations. --- ###**Three, behavioral habits** 1. **Anti-tracking technology** -Disable browser cookies/JavaScript and use privacy plug-ins (uBlock Origin, NoScript). -Use a search engine: DuckDuckGo or SearX (no search history is recorded). -Avoid using Google/Apple accounts to log in to anonymous services. 2. **Metadata protection** -Image/file: remove metadata (tools such as ExifTool). -Document editing: replace Microsoft Office with LIBROFFICE (reduce hidden information). 3. **Anti-fingerprint recognition** -Use browser anti-fingerprint extensions (such as CanvasBlocker). -Tor browser enables anti-fingerprint function by default. --- ###**Fourth, precautions** 1. **Legal compliance** - The technology of concealing identity may be abused, please strictly abide by the laws of your country/region. -Avoid engaging in any illegal activities (such as hacking, slander, fraud). 2. **No absolute anonymity** -Advanced opponents (such as national-level monitoring) may be traceable through comprehensive means such as traffic timing analysis and device fingerprints. -Avoid logging in to your personal account or disclosing related information in an anonymous environment. 3. **Physical security** -Anonymous operations may cause monitoring concerns, and attention needs to be paid to the isolation between real behavior and digital identity. --- ###**Five, resource reference** -**Tor project Official Website**:https://www.torproject.org -**PrivacytoolsIO Guide**:https://www.privacytools.io -**Tails operating system**:https://tails.boum.org Please always use technology for legal and ethical purposes, and be aware of the line between privacy protection and abuse.
