Tatort Internet: Edition 2022

1. 00:00I am pleased to welcome you to the 6th
2. 00:02week in our openhpi course Crime Scene Internet in this last week of our openhpi course
3. 00:08of our course will be about privacy and data protection.
4. 00:14When we are on the internet are not and see them.
5. 00:17Yes, that was our picture of how he as a user with the different
6. 00:20devices the services from the internet structure
7. 00:24infrastructure with the corresponding
8. 00:27infrastructure components and when we are on the road
9. 00:32and use a service we leave very very
10. 00:36various traces also in various ways on
11. 00:39different levels in the infrastructure in the services and other
12. 00:44so and the question,
13. 00:46how is it with these digital tracks?
14. 00:49What do they say about us is which is actually necessary
15. 00:54so every interaction with a networked digital system generates such a ticket.
16. 00:59Tracking, that can be quite obvious,
17. 01:02so if you send an e-mail send, then of course it's obvious,
18. 01:06if they stand there as sender or if they stand you as recipient,
19. 01:09then somehow the parties involved in this access
20. 01:13have access to this open infrastructure is visible,
21. 01:16they have sent each other sent themselves an e-mail,
22. 01:20but even if they start going into the e-mail,
23. 01:24so if your ISP assigns you your Internet Service Provider 1 from your IP address,
24. 01:33to be able to move around on the Internet then at the let
25. 01:37of course with all their movements,
26. 01:40visible to the Internet Service Provider,
27. 01:44who has to make this connection for you. connection for you.
28. 01:48He has to make sure,
29. 01:50that they can use the Internet is Internet you can use there,
30. 01:54so it's quite obvious that it clearly can't be changed,
31. 01:58but there are also many thick. All the traces that they leave behind less obviously,
32. 02:03so, for example, if there's this of the login data from Facebook or these shares
33. 02:13button from Twitter on a on a web page,
34. 02:17then the Twitter or the facebook people every move,
35. 02:24that they make on this on this website,
36. 02:28you have registered via , haven't you?
37. 02:30You have accessed this page via the share functionality of other users to this page
38. 02:36also advertising banners from advertising service providers still fit their
39. 02:41traces and in fact we as users often do not know,
40. 02:45where our data has ended up,
41. 02:49who stores the who processes the
42. 02:53Who might also trade this data and sells it to interested parties.
43. 02:59interested parties when surfing the web when using
44. 03:04apps from smartphones of Hells Treckers of Smart
45. 03:08device is fine plenty of data traces on and the data traces just need technical,
46. 03:14because they have to record the communication in the commands need to be captured,
47. 03:17that's the log data in your computer anyway and that data then makes it very easy
48. 03:23to create such a movement profile or a usage profile exactly for this person,
49. 03:28when did they do what,
50. 03:31i.e. which websites were visited and when,
51. 03:35how often were they visited, how long were they visited,
52. 03:38how did the user movement within an application,
53. 03:42so, what was he he was doing on Facebook,
54. 03:44what was the user doing on Twitter,
55. 03:48if I give her that then and that happens to you of this data as well with the data and
56. 03:56the data traces live in the physical world for example about
57. 04:01surveillance cameras or localisation data,
58. 04:05where we are right now, when that's combined,
59. 04:07it already gives a very precise information about about a person and their behavioural characteristics and
60. 04:15their interests also when is and for what purpose smartphones are used,
61. 04:21what about cloud services that are used,
62. 04:24when are smart devices used,
63. 04:27e.g. household appliances smart household appliances fitness trackers health trackers,
64. 04:32what about payment, if you pay by card,
65. 04:36when they use in the ground system,
66. 04:38when was what amount Amount transferred to whom,
67. 04:44so these are all things pay on the internet?
68. 04:47So what's clear then,
69. 04:50because they buy it's really a very comprehensive a very comprehensive trail situation,
70. 04:58where you can reconstruct reconstruct,
71. 05:03what they did, with with whom they did what,
72. 05:06what you are and different there,
73. 05:10so a bit into the NDL privacy issues,
74. 05:14how is that there with the protection in the Internet or data protection and we have to
75. 05:19first of all keep the terms properly apart,
76. 05:22so with privacy.
77. 05:25There we are talking about the private, i.e. non public sphere in which every human being.
78. 05:32The right has, unimpaired by external influences to its free
79. 05:37development of his personality of his activities.
80. 05:41This right to privacy is considered a fundamental human right in data protection,
81. 05:50there are different aspects that play a role,
82. 05:54so, on the one hand, there is the aspect,
83. 05:57that the data that is available is not.
84. 05:59be misused can be used for abusive
85. 06:03data processing or storage and possibly being able to use them at some time,
86. 06:07there is the right to informational self-determination and then
87. 06:13there is of course a special protection for all data,
88. 06:16which establish a direct link to a person,
89. 06:21so that is there and the personal rights in the processing of data
90. 06:28and if we think about it today in the digital context,
91. 06:32then this is often associated with the term with the English term
92. 06:35privacy is written and it remains encompassed,
93. 06:41both digital privacy as well as data protection
94. 06:45in the digital space now must be clear to us,
95. 06:47that of course the issue of privacy through the digital
96. 06:53technologies and our movement in the digital world,
97. 06:56it just can't be done that way.
98. 06:59Wonderful internet services organise,
99. 07:02without generating any data usage data accrue,
100. 07:06the question is, so how can we can make this privacy
101. 07:11and protection of our data that we want,
102. 07:14how can we also and to what degree and to what extent in the digital world,
103. 07:22There is an observation that many people are very very critical,
104. 07:26because there e.g. a vaccination register or what should be established
105. 07:31actually a very sensible idea at the same time,
106. 07:35but privately share all your data on Facebook at LinkedIn or at
107. 07:40other websites without thinking.
108. 07:43Yes, who am I giving my data to,
109. 07:45what can he do with this data, so this should now want a bit of this week
110. 07:51we dedicate there in this topic and think about it a bit,
111. 07:55what about privacy and data protection on the Internet?
112. 07:59Well, the digital traces of course contribute contribute to the invasion of privacy when we think about
113. 08:06use an Internet service there is no other way we inevitably leave traces Z at the
114. 08:12Google search and the question is now how does Google deal with this data,
115. 08:16which come to the knowledge namely when did we come and
116. 08:19have searched over and at which term,
117. 08:22how do we deal with it had just said,
118. 08:25that many do not even think about it, that they then, for example.
119. 08:29On a small offer there is to download something for free
120. 08:33or other incentives to data voluntarily,
121. 08:38because it is so convenient,
122. 08:40interacting with others in the social networks deepest
123. 08:44private part details the Sharing with don't know at all clear,
124. 08:50with whom also the correlation of actually unproblematic data
125. 08:55can lead to the violation of privacy that together.
126. 08:59Saying data from different sources and putting it together can reveal things,
127. 09:04that are actually protected by the privacy protection not in the
128. 09:09public or not in the hands of a
129. 09:11Internet company should where and by whom data is processed and stored,
130. 09:16this can then be decisive for be decisive for data protection,
131. 09:20In Germany we have a relatively strict strict European regulation,
132. 09:25the dsgvo which regulates data protection issues they know data protection rules,
133. 09:33they also know the dispute the different opinions on this
134. 09:36in the interpretation of these rules all that is also part,
135. 09:41that we first have to learn in this new digital world.
136. 09:45to move Data Protection Act even before dsgvo,
137. 09:49so, these have been developed.
138. 09:51They are also Germany. Wasn't anything first country,
139. 09:54what am I supposed to do data protection laws national rules, they are also then in the national rules.
140. 09:59Different we are happy,
141. 10:02that the same rules apply in Europe when we also observe in daily life,
142. 10:07that these same rules are interpreted differently interpreted differently in different countries,
143. 10:12but there are, for example, in the USA,
144. 10:15who play a big role in the the digital world there are also differences,
145. 10:21that lead to this,
146. 10:23that things that we rely on in Europe we rely on in Europe are not guaranteed there,
147. 10:28do this week. Well,
148. 10:31we deal with digital technologies,
149. 10:33that capture our movement we want to see on the Internet,
150. 10:36where this data is collected on almost, how does it and then ask about the consequences for the
151. 10:43Privacy for the privacy we discuss different privacy issues,
152. 10:49that simply due to the growing the growing number of networks
153. 10:54home suddenly much more devices in use
154. 10:56are the Smart TV the Smart Home Control of any household appliances electricity blinds the
155. 11:05Smart meters to measure the energy Smart traffic in the world the appliances,
156. 11:12that we carry with us, that thus betray us by the second,
157. 11:15where we are just smartphone smartwatches the fitness tracker and we want to see
158. 11:21what is regulated in this in Germany in the dsgvo,
159. 11:27so this is the programme for the week,
160. 11:30hopefully you're interested now on our big topic, Crime Scene Internet,
161. 11:37because of course this is also an important sphere,
162. 11:42which we have to protect and if then tack attack succeeds in this
163. 11:47heavy penetration from to collect data from this shuttle,
164. 11:51we've seen that in the past few weeks already seen this can be easily abused?
