Hb1hf No that method is not secure, very vulnerable to statistical analysis attacks. There have been even full-blown anonymity networks in the past implementing ideas similar to this, where traffic isn't encrypted, but mixed with random padding traffic, even using algorithms that mimics real user behavior in regard to interest and activity patterns, but all those networks have always been broken using statistical methods. Only sending the traffic through an encrypted tunnel like VPN or even better Tor is still considered secure to mask ones usage. Tor uses padding traffic to mask your activity, but it is sent inside the encrypted tunnel to hinder analysis, and discarded before exiting.
