How to be invisible on Internet
Transcript of How to be invisible on Internet
varied depending on country, e.g.:
Human Rights (blocked in China, ..)
Religion (blocked in Saudi Arabia, UAE, Iran, Bahrain, ...)
Pornography (blocked in Saudi Arabia, UAE, Iran, Bahrain, Singapore, Burma, ...)
Encryption prohibited in Pakistan
When a country’s government controls international connectivity, they can block requests for banned websites
Data Retention Law
The Directive requires Member States to ensure that communications providers must retain, for a period of between 6 months and 2 years, necessary data as specified in the Directive
to trace and identify the source of a communication;
to trace and identify the destination of a communication;
to identify the date, time and duration of a communication;
to identify the type of communication;
to identify the communication device;
to identify the location of mobile communication equipment.
Unfortunately European Union is not an exception!
And freedom is also threatened in Slovakia!
Data retention law is valid in Slovakia
Possibility of Internet censorship - online gambling law proposal
The Slovak government makes impossible to provide end-to-end encrypted calls public services
All Slovak mobile operators use censorship (non-transparent IWF blacklists)
Internet censorship in Romania - online gambling, plans to ban drugs and profanity websites...
Internet censorship possible in Hungary because of new media law
Citizens in the United Kingdom must, upon request, give passwords for decryption of personal system to authorities. Failing to do this can result in imprisonment for up to two years, without evidence of other criminal activity
IWF blacklists are massively used by many ISPs
Do you think the government should have a right to put a camera in every room or place where people communicate?
Why do you think it should have the right to gather and intercept the online or mobile communication of all innocent people?
(Yes, terrorists and criminals use end-to-end secure calls and PGP).
How to defend our freedom?
Plausible deniability is a legal concept. It refers to lack of evidence proving an allegation.
If your opponent lacks incontrovertible proof (evidence) of their allegation, you can "plausibly deny" the allegation even though it may be true.
Use strong encryption!
Always use full disk encryption (dm-crypt, truecrypt with hidden volumes) that makes impossible unlawful forensic analysis
Use PGP/SMIME for email communication encryption instead of plaintext emails
Use secure VoIP (SIP/TLS + SRTP/ZRTP) for voice communication instead of GSM/3G which is broken and intercepted by the government
Use Jabber/SSL + OTR/PGP for secure instant communication
Use encrypted communication (SSL based services like HTTPS, IMAPS, OpenVPN, SSH, ..)
Do not use untrusted proprietary 3rd party services like Skype, ICQ, Facebook, Gmail (use only with email encryption) for sending/receiving of any sensitive information
Use strong anonymization services!
(stay for workshop!)
Never reveal your true identity!
Use anonymization networks (Tor, I2P, Freenet) that provides you strong anonymity based on asymmetrical cryptography
Run you own anonymous website / blog using Tor Hidden Services or I2P
Sanitize your browser fingerprint (privoxy, torbutton)
Use Firefox/Opera/IE9/Safari Private Browsing, Chrome Incognito mode
Block active clientside applets (Java, .NET, Flash, Silverlight, ...)
Protecting against tracking of 3rd party social media (priv3, ShareMeNot)
Disable permanent cookies, history/content caching
Use "privacy-enhanced" live Linux distributions that boots from read-only medium:
Ubuntu Privacy Remix
Use "Bitcoins" for pretty anonymous payments!
Anonymous peer-to-peer distributed and decentralized currency with almost no possibility to shutdown
Probably the only way how you can make any business anonymously
Still possibility of deanonymization attacks
It should be impossible to know the actual identity of anyone in cipherspace. Therefore, it would be impossible to impose any censorship and to enforce any law
NO, you DO NOT choose it - cryptoanarchy exists and will exist regardless whether you like it or not
It is extremely difficult to ban the cryptoanarchy system without banning strong encryption, the other drastic option is to perform 1984-like random "searches" by the police or secret agencies
Tax laws or copyrights cannot be forced, any content can be anonymously shared
Any repression in the society (e.g. "War on Drugs", content restrictions, etc.) supports the cryptoanarchy system
On the other hand liberalization and legalization may weaken its popularity
It seems a bit like anarchy...
no censorship at all !
Anonymization services like Tor, I2P or Freenet allow:
Free and secure communication and Internet access from all dictatorship countries
Bypassing all kinds of censorship (e.g. IWF used by all Slovak mobile operators)
Bypassing EU data retention law that monitor all people
Currently the government makes impossible providing of the end-to-end encrypted telecommunication services (there should be always a "backdoor" for secret agencies)
This can be easily bypassed by SIP/TLS+ZRTP in case of voice calls and PGP/SMIME in case of email/instant communication
Sophisticated criminals and terrorists have already used encrypted technologies - it is easy to configure it
Negative aspects of absolute Internet freedom for the current state:
Impossibility of enforcing copyrights
Completely free-markets (including drugs and weapons)
Ilegal information and content
Thanks and enjoy your Internet freedom!
Do benefits of the anonymous digital world outweigh their disadvantages?
Strong encryption and anonymity makes "plausible deniability" possible!
