使用 TOTP 與 Google Authenticator 實作 Two-Factor authentication

在食衣住行育樂都需要的網路的時候,現代人擁有許多網路帳號,但能記憶的帳號密碼通常只有少數組合,當遇到密碼外洩(e.g.資料庫外洩、病毒側錄密碼),相對的也影響了使用共同帳密的網路服務,對今日資安事件逐漸從惡作劇變往金融犯罪的趨勢,帳號有操作功能,個資,身份(實名化),對盜竊者來說帳號密碼可以產生許多價值。

帳號盜用除了個人影響外,間接牽連的還有親友與網路服務提供者,對網路服務提供者而言,帳號盜用是會提高營運成本與降低使用者信賴度的麻煩事,因此面對使用者規模與服務品質,強化帳號安全逐漸成為不可忽視的事情,Google 於去年底開始提供 2-step verification 做多層次的帳號驗證,別於以往硬體 OTP 的方式,透過 Smartphone 使用軟體(i.e Google Authenticator) 來規模化佈署。

目前得知使用類似軟體驗證機制的服務提供者有


在 Server 端的實作驗證流程不難,未來可能會變成一種常見的帳號驗證方法。

以下參考國外部落格文章與 Google Authenticator Android原始碼 實作 Two-Factor authentication 驗證流程,並釋出伺服器端原始碼

GPS 記錄器、相簿、工具、節點編輯...

GPS應用廣泛,尤其整合了網路資源後能擴展的方向很多,本篇是一則實作測試文,為了偷懶不多作說明與修飾,若你有進一步的興趣請勤奮的點選連結,有很多DEMO可以把玩。

20080412阿里山出遊路線分享(I-gotU GT-100)

[旅程中2個大斷層,跟沒結尾的冏況,所以出現大橫貫與圖片辜兒等精采結局請勿受到驚嚇]
step 1. 安裝i-gotU Desktop
step 2. 將 *.mdb(Link) 放至 C:\Documents and Settings\******\Application Data\MobileAction\GPSTracer 取代 Tracer.mdb
step 3. 選取兩筆track→合併
---------- (分隔線)繼續下列步驟或匯出*.gpx(Link)使用其它軟體後製(edit、gpscoding、gpstagging…)---------
step 4. 於下方的"相簿"右鍵→新增圖片
step 5. 選取圖片右鍵→儲存GPS
step 6. 點選上片track 會重新載入Google Map(Ps. i-gotU Desktop圖片太多(大)可能會當)
step 7. 匯出html,gpx,kml…

一些詞條 (Wikipedia)

GPS tracking
A GPS tracking unit is a device that uses the Global Positioning System to determine the precise location of a vehicle, person, or other asset to which it is attached and to record the position of the asset at regular intervals. The recorded location data can be stored within the tracking unit, or it may be transmitted to a central location data base, or internet-connected computer, using a cellular (GPRS), radio, or satellite modem embedded in the unit. This allows the asset's location to be displayed against a map backdrop either in real-time or when analysing the track later, using customized software. Such systems are not new; amateur radio operators have been operating their free GPS based nationwide realtime Automatic Position Reporting System since 1982.

Data loggers
A GPS logger simply logs the position of the device at regular intervals in its internal memory. Modern GPS loggers have either a memory card slot, or internal flash memory and a USB port. Some act as a USB flash drive. This allows downloading of the data for further analysis in a computer.

GPX
GPX, or GPS eXchange Format is an XML schema designed for transferring GPS data between software applications. It can be used to describe waypoints, tracks, and routes. The format is open and can be used without the need to pay licence fees.
Geotagging:
Geotagging, sometimes referred to as Geocoding, is the process of adding geographical identification metadata to various media such as websites, RSS feeds, or images and is a form of geospatial metadata. This data usually consists of latitude and longitude coordinates, though it can also include altitude, bearing, and place names.
Geocode:
Geocoding is the process of assigning geographic identifiers (e.g., codes or geographic coordinates expressed as latitude-longitude) to map features and other data records
Waypoint
Waypoints are sets of coordinates that identify a point in physical space. For the purposes of terrestrial navigation, these coordinates usually include longitude and latitude, and sometimes altitude (particularly for air navigation).

Track、Route
An ordered collection of points may be expressed as a track or a route. Conceptually, tracks are a record of where a person has been, routes are suggestions about where they might go in the future. So, for instance, there might be timestamps for each point in a track (because someone is recording where and when they were there), but timestamps for each point in a route are unlikely to be provided, because the author is suggesting it, and nobody might ever have travelled it.
KML
Keyhole Markup Language (KML) is an XML-based language schema for expressing geographic annotation and visualization on existing or future Web-based, two-dimensional maps and three-dimensional Earth browsers. KML was developed for use with Google Earth, which was originally named Keyhole Earth Viewer. It was created by Keyhole, Inc, which was acquired by Google in 2004. The name "Keyhole" is an homage to the KH reconnaissance satellites, the original eye-in-the-sky military reconnaissance system first launched in 1976.

KMZ
KML files are very often distributed as KMZ files, which are zipped KML files with a .kmz extension
