The Big Data problem

Big Data is the buzz word of the day. With the Internet extended to all facets of everybody’s everyday life, there are a lot of personal information flowing around. Many companies knew a long time ago how to make use of the personal data of their customers in aiding marketing and sales. There are many […]

They want to know where you are

Location-based services have been growing some years ago, starting from RFID devices.  Initially, they are for industrial use, tracking cargoes, sales items, and sometimes persons using bracelets or identity cards.  RFID are close-proximity devices and signals are read by RFID detectors at close range.  Later, with more powerful detectors and GPS technology, location-based services extended […]

Privacy in the world of big data

Personal data privacy is everyone’s concern.  But our understanding of such may be limited.  Scientific American has an article on this in the November 2013 issue.  It was written by a privacy advocate on privacy in the world of big data.  We may read it bearing in mind his bias, but there is some insight […]

誰在看我的電郵

我曾經不止一次告訴各位,在辦公室用電腦是沒有私隱的。你的系統管理員是有權限看到所有經過伺服器的數據。你在用的安全權限只是管理上的需要,將資訊分類。試想想如果你忘記了戶口密碼,系統管理員是可以幫助你解決的。他當然亦可幫助機構解決你。但我們通常都覺得資訊安全是理所當然,自己亦沒有什麼秘密不可告人,所以大家都當不時發生的洩密醜聞是花邊新聞,與己無關。 斯諾登事件其實性質一樣。網上流動的數據被監察是正常的事。正如聲音或無線電訊號在大氣傳播,人人都可接收到。斯諾登事件成為政治事件, 全因美國政府的虛偽,雙重標準,指責他人入侵網絡,但其實她自己一直在做。斯諾登雖然只是將大家已知的秘密說出來,但他有官方文件在手, 醜聞就升級了。 剛看到下面林煒舜的文章。雖然他並沒有說什麼秘密,但他以自身經驗再印證出在機構內員工通訊是沒有私隱的,公司是可以隨時翻看電郵,網頁瀏覽記錄,以至硬碟上的檔案。他更開章明義,說明機構的思維,為何要監察員工,有何益處。這樣說來,機構就可理直氣壯的做,正如美國國務卿所說,一點都不稀奇。 根據美國政府的解釋,我們亦是想當然的假設自己只是香港七百萬人中的一員;數據無限,怎會千揀萬揀來看我的電郵。最多只是統計數據中的一 個數字。但林博士的解釋,機構是有誘因,有動機,有目的和有誠意來看你的電郵。根據現代管理學,人力資源管理是需要知道員工的變化,包括他們個人情緒的變化,對公司前景看法的變化,對目前崗位滿意度的變化。以前一些勤力的人力資源經理會巡視工作間,會見員工,問卷調查,做質量圈等;但都不保證資訊準確。現代科技進步了,監察電郵可算是一個不具爭論性的方法來了解員工,不過當然是要秘密進行。雖然如此,但電郵流量仍是大得不得了。我想不會有機構能監看所有電郵;抽樣檢查就有可能,有些大機構還可能會過濾一些敏感名詞來選擇監看。 但如果你是一個受注視的員工,被監看的機會就會以幾何級數爆高。斯諾登都爆料說高官、議員、學者、領事人員和活躍人士是全部被監看。 ********** 商管心理學: 監察員工的電郵? 資本壹週 – 2013年6月28日週五香港時間上午6:00 林煒舜   臨床心理學博士 叛諜追擊、走佬特工,不論你用哪套美國電影的名字來形容斯諾登來港爆料事件,這宗事件充滿娛樂性是不爭的事實,至少為從來無資格涉足世界政壇的香港,帶來了罕有的刺激。這事件的本質,是美國政府原來一直秘密監察全球電郵。由於美國平日總扮演批評別國不尊重人權的角色,這事爆出來,令奧巴馬政府格外尷尬。 但平心而論,這類監察和你我可說無關,即使我和你的電郵都在監察的範圍,大家都明白,實際上沒有人有興趣去分析我們的電郵。就算被抽中分析,對我們也全無影響,除非我們另有不為人知的身分,例如你是塔利班,或我是俄羅斯特工。所以,美國監察電郵只是侵犯了我們的私隱,對我們則沒有實質影響。 可是,若一間公司監察員工的電郵,情況就不同了。首先,公司管理層能否做到監察員工電郵呢?答案不言而喻。現時大部分中小企,為了體面, 都有屬於公司的電郵地址,反正都是免費的。但有些稍具規模的企業,用的卻不是街外的免費伺服器,而是自己租用的伺服器。你在公司內,用公司的電腦,以公司的電郵和別人通訊,你認為公司有能力監察你嗎?當然,公司會否這樣做是另一回事,但能力上絕對可做到。甚至,即使你在公司內用自己的手提電腦,以自己的雅虎電郵和人通訊,要監察也非無可能。就我所知,本港有一家學術機構,就有這樣的準備。只要校方覺得有需要,經過一定的程序取得行政批准,隨時可翻查任何一位員工在某日某時, 發出過甚麼電郵、瀏覽過甚麼網頁。 反過來說,假設一家大企業的管理層,不惜侵犯私隱,派專人秘密監看公司員工的電郵,有沒有實際作用?這樣做當然是要不得的,但我還是要說:有用。 它最重要的作用,不是可知道誰和誰搞婚外情,而是可知道員工的變化。員工個人情緒的變化,員工對公司前景的看法的變化,員工對目前崗位滿意度的變化。在商業管理的角度,若能準確掌握這些資訊,並以這些資訊為基礎,作出適當的職位、分工、福利等調整,對於員工的穩定和士氣,自然大有幫助。我絕不鼓勵監看電郵,但既然了解員工的變化這麼有用,管理人員該做的,自然是用不具爭論性的方法,盡量了解自己的員工了。 **********

Argus is watching you

We saw in many movies that people were being tracked by spy satellites.  Though it is widely believed that such technology would really be available as we saw many high resolution pictures of the Earth taken by satellites, we are not too worried about us being seen as satellites are expensive.  Unless you are a […]

Tracking phobia

The W3C Tracking Protection Working Group is still debating on the do-not-track saga, which I mentioned in a blog article earlier.  They have been on the negotiation table for two years with results nowhere in sight.  Online advertisers advocate control on the use of tracked data.  Privacy advocates want no track at all.  On the […]

Do not track me

Amendments to the Personal Data (Privacy) Ordinance will be effective on 1 April 2013.  Companies are required to notify their customers about using their personal data for direct marketing.   Citizens of Hong Kong received notification of this use from many companies in March.  They will be presumed to have given consent to such if objection […]

Mickey Mouse is following you

Your personal data privacy is constantly invaded by various parties; to many of those you voluntarily and happily give out personal data.  Who else is the most likely party than your favourite games and toys.  IT World recently disclosed that the Disney World is planning to improve the fun and her services this Spring by […]

Reality Mining

Scientific American in its December 2012 issue reported on Ten World Changing Ideas which are innovations that are radical enough to alter our lives in the near future.  These ideas are not pie in the sky.  They are practical breakthroughs that have been proven or prototyped and are poised to scale up.  This article is […]

Your car may leak your personal data

You may be very careful with your personal data.  But in the near future, when you drive, your car may leak your personal data to the world. This is a planned scenario revealed in the IFA 2012 Consumer Electronic Show in Berlin.  You may see the full article in IT World.  In a joint panel […]
