用舊D的菲林咪算lor...何必追求科技, 係都要scan lei....

By the way, it is always possible for your computer to be hacked, once it's connected to the internet. What I could do is simply hope that others won't be interested in hacking my computer, or sending me a virus, or interested in my photos, etc... . Therefore, I am not so comfortable in making $$ transaction via internet...

錯啦沙兄,其實係基於rules#2"如果會錯就一定有錯"引申出黎啫:

如果有computer security就一定有破解方法,如果一個電腦無I/O device port既係可以做到無破綻既電腦出黎架.但好可惜,你打緊果個kleyboard,睇緊既monitor,推緊既micky,上緊網既有線或無線lan都係I/O port既一種.

其實就等如鎖完開得番既鎖就一定有用鎖匙以外既方法開得到,問題係要用幾耐咁話同時間之嘛啫.而physical既鎖重因為要modify唔同既鎖匙同鎖膽combination要用實物都仲有少少難度,而logical鎖則係可以virtual modify,又唔駛要真既物料,所以好容易.而且一般電腦一開機就有幾萬個I/O port.其實係封唔晒架.

有冇搞錯呀？煩唔煩喲呀？難道宇宙尚有第三條終極真理 -- 天下無破解唔到嘅comupter security?

Split the file into N piece, put them in N different place.  N/2 of the places is remember by you, the other N/2 places is remember by your partner.

In order to get the content, they will need to have all the pieces togather, which means bot of you will have to leak the information out.

乜野password都無用,以而家一般家用intel core 2既速度,兩日內12位既password即死.一個星期內幾乎無乜password唔爆.

DRM其實經已死埋好耐,只係個stream比較麻煩d之嘛:

總之係software既限界入面,係無野100%secure架啦.

無用嫁，假如光碟落係懂電腦人的手中，甚麼password都通通無用。

至於movie，據說微軟的DRM技術，至今仍未有人能破解：

但係難保將來有電腦知識分子都crack左佢。

要保密？放夾萬啦沙冠希。
