PII_type: EMAIL

Exploration_sql:
The following columns may contain email addresses:
- BOOKMARKS: ACCOUNT_NAME, ACCOUNT_TYPE
- INTERNET_SYNC: SYNC_KEY
- SYNC_STATE: account_name
- TABS: ACCOUNT_NAME

You can use the following SQL query to search for email addresses in these columns:
```sql
SELECT ACCOUNT_NAME FROM BOOKMARKS WHERE ACCOUNT_NAME REGEXP '[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}'
UNION ALL
SELECT ACCOUNT_TYPE FROM BOOKMARKS WHERE ACCOUNT_TYPE REGEXP '[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}'
UNION ALL
SELECT SYNC_KEY FROM INTERNET_SYNC WHERE SYNC_KEY REGEXP '[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}'
UNION ALL
SELECT account_name FROM SYNC_STATE WHERE account_name REGEXP '[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}'
UNION ALL
SELECT ACCOUNT_NAME FROM TABS WHERE ACCOUNT_NAME REGEXP '[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}'

PII_Prompt: a unique identifier for a destination to which electronic mail (email) can be sent and received over the internet; examples include jane.doe@example.com, john.smith@provider.net, dev-team@startup.io, and user.name+label@domain.org


PII_type: PHONE

Exploration_sql:
Based on the schema of the available tables, the following columns may contain US phone numbers:
- In the BOOKMARKS table: URL, TITLE, TAGS
- In the INTERNET_SYNC table: SYNC_KEY
- In the SYNC_STATE table: SYNC_VALUE
- In the TABS table: TAB_URL, TAB_TITLE
- In the android_metadata table: No relevant columns

Now, I will construct SQL queries to search for US phone numbers in these columns.
```sql
SELECT URL FROM BOOKMARKS WHERE URL REGEXP '\+?[0-9]{1,4}[- .]?\(?[0-9]{1,3}?\)?[- .]?[0-9]{1,4}[- .]?[0-9]{1,4}[- .]?[0-9]{1,9}'
UNION ALL
SELECT TITLE FROM BOOKMARKS WHERE TITLE REGEXP '\+?[0-9]{1,4}[- .]?\(?[0-9]{1,3}?\)?[- .]?[0-9]{1,4}[- .]?[0-9]{1,4}[- .]?[0-9]{1,9}'
UNION ALL
SELECT TAGS FROM BOOKMARKS WHERE TAGS REGEXP '\+?[0-9]{1,4}[- .]?\(?[0-9]{1,3}?\)?[- .]?[0-9]{1,4}[- .]?[0-9]{1,4}[- .]?[0-9]{1,9}'
UNION ALL
SELECT SYNC_KEY FROM INTERNET_SYNC WHERE SYNC_KEY REGEXP '\+?[0-9]{1,4}[- .]?\(?[0-9]{1,3}?\)?[- .]?[0-9]{1,4}[- .]?[0-9]{1,4}[- .]?[0-9]{1,9}'
UNION ALL
SELECT SYNC_VALUE FROM SYNC_STATE WHERE SYNC_VALUE REGEXP '\+?[0-9]{1,4}[- .]?\(?[0-9]{1,3}?\)?[- .]?[0-9]{1,4}[- .]?[0-9]{1,4}[- .]?[0-9]{1,9}'
UNION ALL
SELECT TAB_URL FROM TABS WHERE TAB_URL REGEXP '\+?[0-9]{1,4}[- .]?\(?[0-9]{1,3}?\)?[- .]?[0-9]{1,4}[- .]?[0-9]{1,4}[- .]?[0-9]{1,9}'
UNION ALL
SELECT TAB_TITLE FROM TABS WHERE TAB_TITLE REGEXP '\+?[0-9]{1,4}[- .]?\(?[0-9]{1,3}?\)?[- .]?[0-9]{1,4}[- .]?[0-9]{1,4}[- .]?[0-9]{1,9}'


PII_type: USERNAME

Exploration_sql:
Based on the schema of the tables, the following columns may contain usernames:
- BOOKMARKS: ACCOUNT_NAME
- INTERNET_SYNC: SYNC_KEY
- SYNC_STATE: account_name
- TABS: ACCOUNT_NAME
- android_metadata: No relevant columns for usernames

To search for possible usernames, you can use the following SQL query:
```sql
SELECT ACCOUNT_NAME FROM BOOKMARKS WHERE ACCOUNT_NAME REGEXP '\\b[a-zA-Z][a-zA-Z0-9._-]{2,51}\\b'
UNION ALL
SELECT SYNC_KEY FROM INTERNET_SYNC WHERE SYNC_KEY REGEXP '\\b[a-zA-Z][a-zA-Z0-9._-]{2,51}\\b'
UNION ALL
SELECT account_name FROM SYNC_STATE WHERE account_name REGEXP '\\b[a-zA-Z][a-zA-Z0-9._-]{2,51}\\b'
UNION ALL
SELECT ACCOUNT_NAME FROM TABS WHERE ACCOUNT_NAME REGEXP '\\b[a-zA-Z][a-zA-Z0-9._-]{2,51}\\b'

PII_Prompt: a username is a short textual identifier chosen by a user to represent their account or public handle within an application or service it is stored as plain text contains no whitespace does not include a domain component and is intended for human recognition rather than internal system uniqueness

Exploration_sql:
Based on the schema of the tables, the following columns may contain person names:
- BOOKMARKS: TITLE, TAGS
- INTERNET_SYNC: SYNC_KEY
- SYNC_STATE: data
- TABS: TAB_TITLE

To search for person names in these columns, you can use the following SQL query:

```sql
SELECT TITLE AS person_name FROM BOOKMARKS WHERE TITLE REGEXP '[A-Za-z][A-Za-z\s\.\-]{1,50}'
UNION ALL
SELECT TAGS AS person_name FROM BOOKMARKS WHERE TAGS REGEXP '[A-Za-z][A-Za-z\s\.\-]{1,50}'
UNION ALL
SELECT SYNC_KEY AS person_name FROM INTERNET_SYNC WHERE SYNC_KEY REGEXP '[A-Za-z][A-Za-z\s\.\-]{1,50}'
UNION ALL
SELECT data AS person_name FROM SYNC_STATE WHERE data REGEXP '[A-Za-z][A-Za-z\s\.\-]{1,50}'
UNION ALL
SELECT TAB_TITLE AS person_name FROM TABS WHERE TAB_TITLE REGEXP '[A-Za-z][A-Za-z\s\.\-]{1,50}'

PII_Prompt: a loosely structured human name-like strings that typically consist of a first name, a first name and a last name, and may also include middle names, initials, prefixes (e.g., Mr., Dr.), and suffixes (e.g., Jr., Sr.)

Based on the schema of the available tables, there is no specific column that directly indicates the presence of a US postal address. However, we can search through text fields in these tables to find possible US postal addresses. Let's search through the text fields in these tables for US postal addresses.
