Private.sh is new search service who promises not to track you. According to their page it uses a procedure five steps for every search to ensure your privacy is protected by encryption.
So we are talking about the most private web search engine.
How does it protect you?
Originally the search query is encrypted locally on your computer. Using client-side Javascript, your search term is encrypted using the public key of the Search Provider – meaning that Private.sh cannot see what you are searching for and only the search provider can decipher it.
Immediately after public IP is hidden by proxy. Private.sh protects your privacy and transfers only the encrypted search term to the search provider so that no user tracking profile can be created using IP fingerprinting.
The search provider decrypts the query and encrypts the search results
The search provider takes the encrypted search term, decrypts it, and then finds the searching results. The results are then encrypted with the public key, so only your browser can decrypt the results.
The encrypted results are returned via the Private.sh proxy
The search results are returned to the browser via Private.sh proxy, so the search provider doesn't communicate directly with you.
Finally, the results are decrypted locally on your computer
The search results are decrypted from your browser using JavaScript.
The service code is open. So with published code, everything is open to scrutiny by anyone interested.
The website and service extension are developed by technologies open source and can be easily tested and improved through a project coming soon.
