• How should I write my privacy notice for Matomo Analytics under GDPR ?

  24 avril 2018, par InnoCraft

  Important note : this blog post has been written by digital analysts, not lawyers. The purpose of this article is to show you an example of a privacy notice for Matomo under GDPR. This work comes from our interpretation of the UK privacy commission : ICO. It cannot be considered as professional legal advice. So as GDPR, this information is subject to change. We strongly advise you to have a look at the different privacy authorities in order to have up to date information.

  A basic rule of thumb is that if you are not processing personal data, then you do not need to show any privacy notice. But if you are doing so, such as processing full IP addresses, then a privacy notice is required at the time of the data collection. Please note that personal data may also be hidden, for example, in page titles or page URLs.

  In this blog post, we will define what a privacy notice is according to GDPR and how to write it if you are using Matomo and you are processing personal data.

  What is a privacy notice under GDPR ?

  One of the most important rights that a data subject has under GDPR, is the right to be informed about the collection and use of their personal data.

  Here is what ICO is saying about the privacy notice :

  “You must provide individuals with information including : your purposes for processing their personal data, your retention periods for that personal data, and who it will be shared with. We call this ‘privacy information’.”

  “When you collect personal data from the individual it relates to, you must provide them with privacy information at the time you obtain their data.”

  Note that a privacy notice is different from a privacy policy.

  The privacy notice has to include :

  • the reasons why you are processing the personal data
  • for how long
  • who the different parties you are going to share them with are

  So whatever lawful basis you are using (explicit consent or legitimate interest), you need to have a privacy notice if you collect personal data.

  What does this privacy notice look like ?

  ICO is providing best practices in order to display the information :

  • a layered approach
  • dashboards
  • just-in-time notices
  • icons
  • mobile and smart device functionalities

  Once more, it really depends on the data you are processing with Matomo. If you wish to track personal data on the entire website, you will probably have an upper or footer privacy notice such as :

  

  If you wish to process specific data, you could also insert just-in-time notices such as :

  

  What is the information you need to disclose to the final user ?

  To us, there are two things to distinguish between the privacy notice and the privacy policy.

  According to ICO, the privacy notice needs to include the 3 following elements :

  • the reasons why you are processing the personal data
  • for how long
  • who are the different parties you are going to share them with

  But you also need to inform them about :

  • The name and contact details of your organisation.
  • The name and contact details of your representative (if applicable).
  • The contact details of your data protection officer (if applicable).
  • The purposes of the processing.
  • The lawful basis for the processing.
  • The legitimate interests for the processing (if applicable).
  • The categories of personal data obtained (if the personal data is not obtained from the individual it relates to).
  • The recipients or categories of recipients of the personal data.
  • The details of transfers of the personal data to any third countries or international organisations (if applicable).
  • The retention periods for the personal data.
  • The rights available to individuals in respect of the processing.
  • The right to withdraw consent (if applicable).
  • The right to lodge a complaint with a supervisory authority.
  • The source of the personal data (if the personal data is not obtained from the individual it relates to).
  • The details of whether individuals are under a statutory or contractual obligation to provide the personal data (if applicable, and if the personal data is collected from the individual it relates to).
  • The details of the existence of automated decision-making, including profiling (if applicable).

  Pretty long, don’t you think ? In order to reduce it, you can either adopt a layered approach where your “pop-up” window will act as a drop down menu. Or from what we understood, page 5 of this document provided by ICO, a privacy notice can link to a more detailed document, such as a privacy policy page.

  Examples

  Let’s take the example of a website which tracks the non-anonymised full IP address, and using User ID functionality to keep track of logged-in users. Under GDPR, the owner of the website will have to choose either to process personal data based on “Legitimate interests” or on “Consent”. Here is how it will look like :

• Error method describe failed : 401 unauthorized

  5 juillet 2023, par EYakoumi

  I am trying to connect to an RTSP camera using opencv c++ but for this specific camera i am getting the following message whenever i try to connect

  


  Error method describe failed : 401 unauthorized

  


  the code i used to connect is as follows :

  


  VideoCapture camera;&#xA;&#xA;camera.open("rtsp://ssdadmin:S5D.admin@<ip>:<port>/live/221067c3-fa55-4c44-819d-47b54497cfc9", CAP_FFMPEG);&#xA;</port></ip>

  


  where the username is ssdadmin and the password is S5D.admin
and used the correct values for ip and port

  


  I read here that opencv might need url encoding for the password special characters so i switched the "." character in the password to %2E (S5D%2Eadmin) again same problem. knowing that accessing the same url in vlc without encoding the character works.

  


  what am i missing in the address to get the unauthorized message

  


• Save and re-stream RSTP video as straight UDP

  30 septembre 2013, par user1701362

  I am trying to write a program that will connect to a RTSP video source and redirect the video data to another location using UDP. I am also saving the RTSP packets to be able to replay the video stream at a latter moment in time as well. Right now my program can connect to the RTSP video stream and redirect and save, but when I try to look at the redirected video I get nothing using VLC.

  Currently the program just strips out the datagram from the RTSP video packets it receives in its open UDP socket and re-sends them using this code using the boost asio library.

  newVideoSocket->send_to(&dg.data[0], dg.data.size() ,Endpoint);

  When I look at the traffic using Wireshark I see that it is actually sending the data to the new address and it is recognized as a UDP packet, but when I try and view the video using VLC nothing happens. The video stream is Mpeg4 with the video encoded as H.264 and VLC can play it.

  I have tried to connect to the redirected stream as UDP and as RTP at both multicast and unicast addresses but have had no success. Do I need to add or take something out of the datagram before I resend it ? Or is it something wrong with how I am tring to view it in VLC ? Thanks for the help.
