Software Taxonomy of Faults

Category Option Rationale
Recurring unknown (a) The software failure incident related to a privacy bug in Google's Home Mini smart speaker is specific to Google. There is no mention in the article of a similar incident happening before within the same organization. (b) The incident involving the privacy bug in the Google Home Mini smart speaker does not indicate that a similar incident has happened before at other organizations or with their products and services. The focus of the article is on Google's response to the flaw in their own product.
Phase (Design/Operation) design (a) The software failure incident in Article 63996 was related to the design phase. The incident was caused by a privacy bug in the Google Home Mini smart speaker, which allowed some units to record sounds at random times and transmit the audio to Google's servers. This flaw was a result of a design issue in the top touch functionality of the device, which was addressed by Google through a software update and the permanent removal of the top touch feature [63996]. (b) The software failure incident in Article 63996 was not related to the operation phase but rather to a design flaw in the system that allowed unauthorized recordings to be sent to Google's servers.
Boundary (Internal/External) within_system The software failure incident related to the Google Home Mini privacy bug falls under the within_system boundary. The flaw that allowed some units to record sounds at random times and transmit the audio to Google's servers was a result of an internal issue with the device's touch functionality [63996].
Nature (Human/Non-human) non-human_actions (a) The software failure incident in Article 63996 was due to non-human actions. The incident was caused by a privacy bug in the Google Home Mini smart speaker, which allowed some units to record sounds at random times and transmit the audio to Google's servers. This flaw was not introduced by human actions but was a result of a bug in the software [63996].
Dimension (Hardware/Software) hardware, software (a) The software failure incident in Article 63996 was primarily due to a hardware issue. The incident involved a privacy bug in Google's Home Mini smart speaker, where a flaw in the hardware allowed some units to record sounds at random times and transmit the audio to Google's servers. Google addressed this issue by permanently removing the top touch functionality of the device through a software update [63996].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident described in Article 63996 was non-malicious. It was a privacy bug in Google's Home Mini smart speaker that allowed some units to record sounds at random times and transmit the audio to Google's servers. Google took the issue seriously and issued a software update to address the flaw, demonstrating that the incident was not caused by malicious intent but rather by a technical flaw in the software [63996].
Intent (Poor/Accidental Decisions) poor_decisions (a) The intent of the software failure incident was poor_decisions. Google made the decision to permanently remove all top touch functionality from the Home Mini smart speaker after a privacy bug was discovered. This flaw allowed some units to record sounds at random times and transmit the audio to Google's servers. The decision to remove this functionality was made to address the issue and ensure user privacy and product quality concerns were taken seriously [63996].
Capability (Incompetence/Accidental) development_incompetence (a) The software failure incident related to development incompetence is evident in the article as a privacy bug in Google's Home Mini smart speaker allowed some units to record sounds at random times and transmit the audio to Google's servers. This flaw was discovered by Artem Russakovskii, founder of Android Police, who found that his review unit was waking up "thousands of times a day" to send recordings to Google after registering "phantom" touches on the top of the device. Google issued a software update to address the issue, permanently removing all top touch functionality to ensure user privacy and product quality [63996]. (b) The software failure incident related to accidental factors is also present in the article as Google mentioned that they only received a few reports of the issue and wanted to ensure complete peace of mind for users. The flaw allowing the Home Mini to record and transmit audio at random times was not intentional but accidental, leading to the decision to limit the device's control to voice commands only [63996].
Duration permanent (a) The software failure incident in Article 63996 was considered permanent. Google decided to permanently remove all top touch functionality from the Home Mini smart speaker after the discovery of a privacy bug that allowed some units to record sounds at random times and transmit the audio to Google's servers. This decision was made to address the flaw and ensure user privacy and product quality concerns were taken seriously [63996].
Behaviour other (a) crash: The software failure incident in Article 63996 was not a crash where the system loses state and does not perform any of its intended functions. Instead, the issue was related to a privacy bug that allowed some units of Google Home Mini to record sounds at random times and transmit the audio to Google's servers [63996]. (b) omission: The incident did not involve omission where the system omits to perform its intended functions at an instance(s). Instead, the flaw in the software led to unintended recordings being made and transmitted to Google's servers [63996]. (c) timing: The software failure incident was not related to timing issues where the system performs its intended functions correctly but too late or too early. The issue was more about unauthorized recordings being made due to a privacy bug [63996]. (d) value: The incident did not involve a failure due to the system performing its intended functions incorrectly. The flaw in the software led to the unintended recording and transmission of sounds, rather than incorrect performance of its intended functions [63996]. (e) byzantine: The software failure incident did not exhibit behavior characteristic of a byzantine failure, where the system behaves erroneously with inconsistent responses and interactions. The issue was more focused on the privacy bug that allowed unauthorized recordings to be made and sent to Google's servers [63996]. (f) other: The behavior of the software failure incident in Article 63996 can be categorized as a privacy breach due to a flaw in the software that allowed the Google Home Mini to record sounds at random times and transmit the audio to Google's servers without user consent. This behavior falls under the category of a privacy violation rather than the options (a) to (e) mentioned above [63996].
