| Nice Work!
would you please briefly explain the contribution of your work in respect to avoiding sexual offenses against children? |
A comprehensive correction strategy is proposed for policymakers to fight against criminal learning events on the dark web, where the bulk of unethical activities occur. Policy makers can use the four environmental aspects mentioned in this paper: family, school, community, and social values to improve the current living environment of children, prevent children from using the Internet to commit sexual crimes, and prevent other possible crime factors. . |

| Hi, thanks for the sharing.
On the topics of "cybercrime activity increasingly uses encryption and
anonymous technologies", how does law enforcement in your region tackles the challenges?
Thanks. |
In our country, Bitcoin is usually used as an anonymous and encrypted criminal tool on the Internet. In response to this situation, we propose to use three aspects to solve the problem:
1. Develop Bitcoin transaction records and real-time tracking technology:
In a Bitcoin transaction, users usually use many addresses. For example, Sender may send Bitcoin from multiple addresses and receive new addresses, but all addresses are controlled by the user’s private key, so deliver here Several addresses involved in the process belong to the same user. After determining the address used by a user, and then comparing these addresses with other transactions, you can further determine which transactions belong to the same user
2. Analyze and establish the characteristics of illegal user transactions:
After mastering the user-level data, we can further analyze the transaction behavior and form of legal and illegal users, and analyze the transaction characteristics of the latter.
3. Combining Internet and traditional investigation techniques:
After the aforementioned Bitcoin transaction records and real-time tracking technology and filtering of suspicious illegal users, it can theoretically be further connected to their social network and physical location and other data to learn their true identity, but the challenges encountered by traditional cybercrime are the same. Illegal users may use (Dark Net) or computer hacking technology to use other people’s computers or transfer to foreign hosts as a springboard to avoid investigators from discovering their identity. Therefore, investigative agencies should continue to strengthen network investigation techniques to break through. limit.
Thank you for your question. |
