User Study Logging

To facilitate our understanding of how to make photo privacy more convenient on popular social media, we ask that users participate in a user study that involves non-identifiable data logging.

For our ease of analysis as well as minimizing impact on end-user performance we outline the following protocol to which we adhere in the released version of the Cryptagram platform.

• shout("CODEC " + testCodec.name());
• severe("UNKNOWN_CODEC");
• shout("DECODE_LEN_ELAPSED_MS " +
• severe("DOWNLOAD_FAILED " + sjcl.hash.sha256.hash(src));
• severe("DOWNLOAD_FAILED " + sjcl.hash.sha256.hash(src));
• shout("FACEBOOK_MODE " + this.state);
• shout("GPLUS_MODE" + this.state);
• shout("HASH_EMBED_CALC " + check + " " + hexHash);
• severe("FAILED_HASH_EMBED_CALC " + check + " " + hash);
• severe("FAILED_DECRYPT " + hash + " " + err.toString());
• shout("DECRYPTED_OUT_LEN " + decrypted.length);
• shout("ENCRYPTED_HASH " + integrity_check_value);
• severe("FAILED_HASH_EMBED_CALC " + check + " " + hash);
• severe("FAILED_DECRYPT " + hash + " " + err.toString());
• shout("HASH_LEN " + hash + " " + decrypted.length);
