In the process of human trafficking, a series of illegal and unethical means are often used to deal with the identity information of trafficked persons. These means include: 1. **Deprivation of identity documents**: Traffickers often forcibly confiscate important identity documents such as passports and ID cards of trafficked persons to prevent them from escaping or seeking help. 2. **Falsification of identity information**: Sometimes, traffickers will falsify the identity information of trafficked persons and change them to someone else's identity in order to control and exploit them. 3. **Using false promises**: Traffickers may lure trafficked persons with false job opportunities or life promises to conceal their true identity and purpose. 4. **Control of communication**: Traffickers often restrict the means of communication of trafficked persons, and in some cases, even prohibit them from contacting the outside world to prevent them from reporting or escaping. 5. **Psychological manipulation**: Through intimidation, violence or psychological manipulation, trafficked persons are made to feel helpless and give up the idea of seeking help. These means not only violate the basic human rights of trafficked persons, but also make the work of combating human trafficking more difficult. Countries and international organizations are working to strengthen laws and policies to more effectively combat human trafficking and protect the rights of victims.
